Lattices from tight equiangular frames

Albrecht Boettcher, Lenny Fukshansky, Stephan Ramon Garcia +2

We consider the set of all linear combinations with integer coefficients of the vectors of a unit tight equiangular $(k, n)$ frame and are interested in the question whether this se…

$p$ -adic quotient sets

Stephan Ramon Garcia, Yu Xuan Hong, Florian Luca +4

For $A \subseteq N$ , the question of when $R (A) = {a / a^{'} : a, a^{'} \in A}$ is dense in the positive real numbers $R_{+}$ has been examined by many authors over the y…

On the similarity of AB and BA for normal and other matrices

Stephan Ramon Garcia, David Sherman, Gary Weiss

It is well-known that $A B$ and $B A$ are similar when $A$ and $B$ are complex square Hermitian matrices. In this note we answer a question of F. Zhang by demonstrating that similari…
