Seminar «Combinatorics, algebraic topology and volumes of polyhedral»
Speaker: Grigory Solomadin, RUDN University
Topic: The proof of sufficiency part for g-theorem (continuation).
Abstract: We will study cyclic polytopes in R^n and the Gale evenness condition. After that, we will prove the sufficiency part of g-theorem by Billera and Lee. For this aim we will use one statement of Macaulay and Stanley from commutative algebra.
