Inverse Extremal Eigenvalue Problems for Multi-Arrowhead Pentadiagonal Matrices

We address the inverse extremal eigenvalue problem (IEEP) for multi-arrowhead pentadiagonal matrices, a structured class that combines pentadiagonal bandwidth with an alternating arrowhead structure. We identify four distinct structural classes based on the orientation and configuration of arrowhead...
