| Abstract: | The multigraded Hilbert scheme parametrizes all homogeneous ideals in a polynomial ring graded by an abelian group with a fixed Hilbert function. In this talk, we'll show that any multigraded Hilbert scheme is smooth and irreducible when the polynomial ring is ZZ[x,y]; this establishes a conjecture of Haiman and Sturmfels. |
