On the Principal Permanent Rank Characteristic Sequences of Graphs and Digraphs

Keivan Hassani Monfared, Paul Horn, Franklin H. J. Kenter +3

The principal permanent rank characteristic sequence is a binary sequence $r_{0} r_{1} \dots r_{n}$ where $r_{k} = 1$ if there exists a principal square submatrix of size $k$ with nonzero…

Graphs with many strong orientations

Sinan Aksoy, Paul Horn

We establish mild conditions under which a possibly irregular, sparse graph $G$ has "many" strong orientations. Given a graph $G$ on $n$ vertices, orient each edge in either direct…
