On Sign Pattern Matrices that Allow or Require Algebraic Positivity

Jean Leonardo Abagat, Diane Christine Pelejo

A square matrix $M$ with real entries is said to be algebraically positive (AP) if there exists a real polynomial $p$ such that all entries of the matrix $p (M) > 0$ . A square sign pa…

Minimum number of non-zero-entries in a $7 \times 7$ stable matrix

Christopher Hambric, Chi-Kwong Li, Diane Christine Pelejo +1

We prove that if a $7 \times 7$ matrix is potentially stable, then it has at least 11 non-zero entries. The results for $n \times n$ matrix with $n$ up to 6 are known previously. We…
