On the combinatorial structure of 0/1-matrices representing nonobtuse simplices
Jan Brandts, Apo Cihangir
A 0/1-simplex is the convex hull of n+1 affinely independent vertices of the unit n-cube I^n. It is nonobtuse if none its dihedral angles is obtuse, and acute if additionally none…

Enumeration and investigation of acute 0/1-simplices modulo the action of the hyperoctahedral group
Jan Brandts, Apo Cihangir
The convex hull of n+1 affinely independent vertices of the unit n-cube Cn is called a 0/1-simplex. It is nonobtuse if none its dihedral angles is obtuse, and acute if additionally…

Geometric aspects of the symmetric inverse M-matrix problem
Jan Brandts, Apo Cihangir
We investigate the symmetric inverse M-matrix problem from a geometric perspective. The central question in this geometric context is, which conditions on the k-dimensional facets…
