- 제목: The face number of a lattice polytope, and toric varieties. 

- 초록: The g-conjecture, proved by Billera and Lee (1981) and Stanley (1980), provides a comprehensive combinatorial characterization of simplicial (or simple) polytopes in terms of their face numbers. Stanley’s contribution to this conjecture employed toric geometry, specifically leveraging the connection between the face numbers of lattice polytopes and a certain topological invariant of (rationally) smooth toric varieties. In this talk, we will outline the key ideas behind this relationship and discuss possible extensions to singular toric varieties. You only need to know how to count face numbers of a polytope and elementary polynomial computations.
