István Tomon, Ramsey properties of semilinear graphs

Wednesday, April 14, 2021 @ 5:00 PM - 6:00 PM KST

Zoom ID: 869 4632 6610 (ibsdimag)

A graph $G$ is semilinear of bounded complexity if the vertices of $G$ are elements of $\mathbb{R}^{d}$, and the edges of $G$ are defined by the sign patterns of $t$ linear functions, where $d$ and $t$ are constants. In this talk, I will present several results about the symmetric and asymmetric Ramsey properties of semilinear graphs. Some interesting instances of such graphs are intersection graphs of boxes, interval overlap graphs, and shift graphs, so our results extend several well known theorems about the Ramsey and coloring properties of these geometrically defined graphs.
