1. # GTC Visions Seminar: Vector-sum theorems, their relatives and applications

Location: MSRI: Simons Auditorium
Speakers: Imre Barany (Renyi Institute of Mathematics)

About hundred years ago, answering a question of Riemann, Steinitz proved the following result. Let B be the unit ball of the Euclidean norm in R^d and assume that V is a finite subset of B and the sum of the elements in V is zero. Then there is an ordering v_1,...,v_n of the elements in V such that all partial sums along this ordering have norm smaller than 2d. I am going to talk about extensions, generalizations, and applications of this remarkable theorem, and some open problems around it.

3. # GFA Main Seminar: Interlacing Families

Location: MSRI: Simons Auditorium
Speakers: Nikhil Srivastava (University of California, Berkeley)

We survey the method of interlacing families of polynomials, with an emphasis on applications to functional analysis and combinatorics. This is a variant of the probabilistic method which relies on properties of real-rooted multivariate polynomials, and sometimes yields much sharper bounds than traditional probabilistic techniques. We will describe how it can be used to prove a sharp version of Bourgain and Tzafriri's Restricted Invertibility Theorem, as well as the existence of Ramanujan graphs of all degrees, and discuss connections to other areas such as operator theory, random matrix theory, and free probability.

5. # Combinatorial Fixed Point Theorems Working Group: Achieving rental harmony with a secretive roommate

Location: MSRI: Baker Board Room
Speakers: Florian Frick (Cornell University)
We will discuss a generalization of the KKM theorem, and thus of Brouwer's fixed point theorem, that implies an optimal envy-free rent division result: the rent of an n-bedroom apartment can be divided among the rooms in such a way that n roommates decide for pairwise distinct rooms; the knowledge of the subjective preferences of only n-1 roommates suffices to accomplish this fair division.

6. # UC Berkeley Colloquium: What is the AdS/CFT correspondence?

Location: 60 Evans Hall
Speakers: Alexander Wright (Stanford University)

http://events.berkeley.edu/index.php/calendar/sn/math.html?event_ID=111587

One of the themes of Maryam Mirzakhani's work is that the dynamics and geometry of individual surfaces are closely tied to moduli spaces of surfaces. Starting from this general perspective, we will focus in on our recent joint work with Mirzakhani and others on the GL(2,R)GL(2,R) action on the Hodge bundle over the moduli space of Riemann surfaces. This action will be presented in a very elementary way in terms of polygons in the plane. We will mention some of the deep connections to other subjects, and will likely touch on joint work with Eskin, Filip, McMullen, and Mukamel.

1. # GFA Postdoc Seminar: Connection between KLS Conjecture and Sampling

Location: MSRI: Simons Auditorium
Speakers: Benjamin Cousins (Georgia Institute of Technology)

The well-known KLS conjecture about isotropic convex bodies was made alongside the search for fast algorithms to sample from a convex body. In this talk, I will give the details behind the connection between the KLS conjecture and the mixing time of a natural random walk; namely, how a positive resolution of the KLS conjecture implies an O(n^2) sampling algorithm for an isotropic convex body.

2. # GTC Postdoc Seminar: Toward a geometric approach to Chapoton triangles

Location: MSRI: Simons Auditorium
Speakers: Thomas McConville (Massachusetts Institute of Technology)
Chapoton introduced several polynomials defined in terms of "Coxeter-Catalan" objects associated to a given root system, and he conjectured several identities among them. These identities were then extended and proved by several authors. Although the polynomials are presented in an abstract combinatorial manner, they have a natural interpretation in terms of Cambrian fans. In this talk, I will present some other fans with no apparent connection to root systems for which Chapoton's polynomials remain combinatorially meaningful. This is from joint work with Alexander Garver.

3. # GTC Graduate Seminar: On the oriented matroid Grassmannians

Location: MSRI: Baker Board Room
Speakers: Nevena Palic (Freie Universität Berlin)

The oriented matroid Grassmannians, later also called MacPhersonians, were introduced in 1993 by Robert MacPherson as a combinatorial analogue to real Grassmann manifolds. The MacPhersonian MacP(r, n) is the order complex of the partially ordered set of all rank r oriented matroids on a labelled set of n elements, ordered by weak maps. It was a crucial ingredient for giving a combinatorial formula for Pontrjagin classes by Gelfand and MacPherson. Moreover, MacPherson constructed a canonical map µ : G(r, n) → MacP(r, n) from the Grassmannian to the oriented matroid Grassmannian. Since then, the main question is whether the map µ is a homotopy equivalence. Some progress towards understanding this map has been made in the literature, but the topology of the MacPhersonian is still unknown.

In this talk some properties of the MacPhersonian will be discussed and main results will be mentioned. This is an ongoing research project.

4. # GTC Main Seminar: Purity and separation for oriented matroids

Location: MSRI: Simons Auditorium
Speakers: Alexander Postnikov (Massachusetts Institute of Technology)

Leclerc and Zelevinsky, motivated by the study of quasi-commuting quantum flag minors, introduced the notions of strongly and weakly separated collections.   These notions are closely related to cluster algebras, double Bruhat cells, and the positive Grassmannian.   A key feature of strongly/weakly separated collections is the purity phenomenon.
We introduce the notion of M-separation, for any oriented matroid M, and investigate its relationship with zonotopal tilings.   We define the class of pure oriented matroids for which the purity phenomenon holds.   It turns out that an oriented matroid of rank 3 is pure if and only if it is isomorphic to a positroid (or, equivalently, positively oriented matroid).   A graphical matroid is pure if and only if it corresponds to an outerplanar graph.   We give a conjectural characterization of pure oriented matroids in terms of forbidden minors and prove it in many cases.
The talk is based on a joint paper with Pavel Galashin.

Location: MSRI: Baker Board Room

In the first seminar, on September 26, we will be discussing the culture of "brilliance" in mathematics research. We ask that everyone read the following Science Magazine article about a 2015 study on this topic: http://www.sciencemag.org/news/2015/01/belief-some-fields-require-brilliance-may-keep-women-out For anyone who is interested in reading in more depth about this, you can find the original article plus two responses attached.

We will spend the first 15-20 minutes of the seminar holding small-group discussions about the article. We will spend the remaining seminar time sharing the results of these initial discussions and discussing ways in which these findings might impact our practices with regard to mentoring, collaboration, and public advocacy.

Location: MSRI: Simons Auditorium
Speakers: Paata Ivanisvili (Princeton University; University of California, Irvine)
Let X be a finite collection of sets. I will speak about how to efficiently count the number of ways that a union of n disjoint elements of X is also an element of X.
We will estimate this number from above in terms of n and the cardinality of X.

18. # GTC Postdoc Seminar: Positroids, posets and polytopes

Location: MSRI: Simons Auditorium
Speakers: Anastasia Chavez (University of California, Berkeley)
*** This is a talk to be given at the Modern Math Workshop, a mini-workshop/conference for a general mathematics audience of undergraduates to young faculty. It will also include a small portion about my experience as a MSRI postdoc in the GTC program. The talk will aim to be 30 min. ***
The introduction and study of positroids, a special class of matroids, was pioneered by Postnikov in his study of the totally nonnegative Grassmannian and has subsequently been applied to various fields such as cluster algebras, physics, and free probability. Postnikov showed that positroids, the matroids realized by full rank $k\times n$ real matrices whose maximal minors are nonnegative, are in bijection with several combinatorial objects: Grassmann necklaces, decorated permutations, Le-diagrams and plabic graphs.
This talk will provide an introduction to the theory of positroids. I will also briefly discuss results utilizing this theory that address questions regarding simplicial polytopes and a family of posets called Unit Interval Orders. These results are the product of collaborations with Felix Gotti and Nicole Yamzon.

20. # GTC Main Seminar: Circuits and Hurwitz action in finite root systems

Location: MSRI: Simons Auditorium
Speakers: Victor Reiner (University of Minnesota Twin Cities)

In a finite real reflection group, two factorizations of a Coxeter element into an arbitrary number of reflections are shown to lie in the same orbit under the Hurwitz action if and only if they use the same multiset of conjugacy classes. The proof makes use of a surprising lemma, derived from a classification of the minimal linear dependences (matroid circuits) in finite root systems: any set of roots forming a minimal linear dependence with positive coefficients has a disconnected graph of pairwise acuteness. Joint work with Joel Brewster Lewis.

49. # Measurably entire functions and their growth

Location: MSRI: Baker Board Room
Speakers: Adi Glucksam (Tel Aviv University)
Let (X,B,P) be a standard probability space. Let T:C\rightarrow PPT(X) be a free action of the complex plane on the space (X,B,P). We say that the function F:X\rightarrow C is measurably entire if it is measurable and for P-a.e x the function F_x(z):=F(T_zx) is entire.
B. Weiss showed in '97 that for every free C action there exists a non-constant measurably entire function. In the talk I will present upper and lower bounds for the growth of such functions.
The talk is partly based on a joint work with L. Buhovsky, A.Logunov, and M. Sodin.
