Inequalities on the joint and generalized spectral and essential spectral radius of the Hadamard geometric mean of bounded sets of positive kernel operators

A. Peperko

Let $Ψ$ and $Σ$ be bounded sets of positive kernel operators on a Banach function space $L$ . We prove several refinements of the known inequalities $$ρ\left(Ψ^{\left( \frac{1}{2} \…

Polynomial convolutions in max-plus algebra

Amnon Rosenmann, Franz Lehner, Aljosa Peperko

Recently, in a work that grew out of their exploration of interlacing polynomials, Marcus, Spielman and Srivastava and then Marcus studied certain combinatorial polynomial convolut…
