Supports for minimal hermitian matrices

Alberto Mendoza, Lázaro Recht, Alejandro Varela

We study certain pairs of subspaces $V$ and $W$ of $C^{n}$ we call supports that consist of eigenspaces of the eigenvalues $\pm ∥ M ∥$ of a minimal hermitian matrix $M$ ($\|M…

Quadratic forms representing the $p$ -th Fibonacci number

Pedro Berrizbeitia, Florian Luca, Alberto Mendoza

In this paper, we show that if $p \equiv 1 (mod 4)$ is prime, then $4 F_{p}$ admits a representation of the form $u^{2} - p v^{2}$ for some integers $u$ and $v$ , where $F_{n}$ is the $n$ th Fibon…
