Paley-like graphs for the Ramsey number

Yuval Wigderson

An earlier version of this paper constructed a family of -vertex -free graphs which we conjectured to have independence number . This conjecture is false…

An improved lower bound on multicolor Ramsey numbers

Yuval Wigderson

A recent breakthrough of Conlon and Ferber yielded an exponential improvement on the lower bounds for multicolor diagonal Ramsey numbers. In this note, we modify their construction…

The uncertainty principle: variations on a theme

Avi Wigderson, Yuval Wigderson

We show how a number of well-known uncertainty principles for the Fourier transform, such as the Heisenberg uncertainty principle, the Donoho--Stark uncertainty principle, and Mesh…

A short proof of the canonical polynomial van der Waerden theorem

Jacob Fox, Yuval Wigderson, Yufei Zhao

We present a short new proof of the canonical polynomial van der Waerden theorem, recently established by Girao [arXiv:2004.07766].

Extremal and Ramsey results on graph blowups

Jacob Fox, Sammy Luo, Yuval Wigderson

Recently, Souza introduced blowup Ramsey numbers as a generalization of bipartite Ramsey numbers. For graphs and , say if every -edge-co…

Multicolor Ramsey numbers via pseudorandom graphs

Xiaoyu He, Yuval Wigderson

A weakly optimal -free -graph is a -regular -free graph on vertices with and spectral expansion , for some fixed .…
