Introduction to Ramsey Theory: Bounds and Examples
Introduction to Ramsey Theory: Bounds and Examples
Seth Eisenberger
Abstract: Introduction to the definition of the Ramsey numbers for two-colorings of graphs, proof of Ramsey’s Theorem for two-colorings, proofs of R(3,3)=6 and R(3,4)=9, lower bound on R(k,k) using probabilistic method, statement of Ramsey’s Theorem for n-colorings.

(1+1)-dimensional TQFT and Frobenius algebras
(1+1)-dimensional TQFT and Frobenius algebras
Yikai Teng
Abstract: n this talk, we introduce the cobordism category, with a focus on 2-dimensional case. Moreover, we show that there is a weak equivalence between the 2d TQFTs and the Frobenius algebras.

Existence and regularity of weak solution
Existence and regularity of weak solution
Yang Zhang
Abstract: Continuing from the last time, we will give the important Sobolev inequality. After that we will give the definition of weak solutions and discuss the existence and regularity of them.
