   Workshop Initial Data and Evolution Problems in General Relativity

   Show All Collapse

   Nov 18, 2013 Monday

   11:00 AM - 12:00 PM   Stability and instability of spatially homogeneous solutions in the T^2 symmetric setting Hans Ringström (Royal Institute of Technology (KTH)) Location MSRI: Simons Auditorium Video Abstract Solutions to Einstein's equations with a high degree of symmetry play an important role in guiding our understanding of general relativity. It is therefore natural to ask: to what extent are these solutions representative? In the talk we give examples both of stability and instability and relate the results to more general conjectures. In particular, we illustrate the strong dependence of the conclusions on the presence/absence of a positive cosmological constant Supplements Ringstorm 173 KB application/pdf Show Detail
