Saturation problems about forbidden $0$ - $1$ submatrices

Radoslav Fulek, Balázs Keszegh

A $0$ - $1$ matrix $M$ is saturating for a $0$ - $1$ matrix $P$ if $M$ does not contain a submatrix that can be turned into $P$ by changing some $1$ entries to $0$ entries, and changin…

Strong Hanani-Tutte for the Torus

Radoslav Fulek, Michael J. Pelsmajer, Marcus Schaefer

If a graph can be drawn on the torus so that every two independent edges cross an even number of times, then the graph can be embedded on the torus.

Polygons with Prescribed Angles in 2D and 3D

Alon Efrat, Radoslav Fulek, Stephen Kobourov +1

We consider the construction of a polygon $P$ with $n$ vertices whose turning angles at the vertices are given by a sequence $A = (α_{0}, \dots, α_{n - 1})$ , $α_{i} \in (- π, π)$ , for $i\in\{…
