#### The largest sum-free subsets of integers

###### Yifan Jing (UIUC)

Abstract: Given $A$ a set of $N$ positive integers, an old question in additive combinatorics asks that whether $A$ contains a sum-free subset of size at least $N/3+\omega(N)$ for some increasing unbounded function $\omega$. In this talk, I will present some recent progress of the conjecture, based on the joint work with Shukun Wu.
