S-hypersimplices, pulling triangulations, and monotone paths

Sebastian Manecke, Raman Sanyal, Jeonghoon So

An $S$ -hypersimplex for $S \subseteq {0, 1, \dots, d}$ is the convex hull of all $0/1$ -vectors of length $d$ with coordinate sum in $S$ . These polytopes generalize the classical hy…

Generalized angle vectors, geometric lattices, and flag-angles

Spencer Backman, Sebastian Manecke, Raman Sanyal

Interior and exterior angle vectors of polytopes capture curvature information at faces of all dimensions and can be seen as metric variants of $f$ -vectors. In this context, Gram's…

The Martin Gardner Polytopes

Kristin Fritsch, Janin Heuer, Raman Sanyal +1

In the chapter "Magic with a Matrix" in \emph{Hexaflexagons and Other Mathematical Diversions} (1988), Martin Gardner describes a delightful "party trick" to fill the squares of a…
