On a conjecture concerning totally extremal ideal Perron similarities

Erica J. Artemis, Pietro Paparella

Identifying ideal Perron similarities is a problem of central interest in the longstanding nonnegative inverse eigenvalue problem (NIEP). A normalized ideal Perron similarity is ca…

Character tables are ideal Perron similarities

David Z. Gershnik, Alexander J. Lewis, Pietro Paparella

An invertible matrix is called a Perron similarity if it diagonalizes an irreducible, nonnegative matrix. Each Perron similarity gives a nontrivial polyhedral cone, called the spec…
