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

Katarina Bogdanović, Aljoša Peperko

We prove new inequalities and equalities for the generalized and the joint spectral radius (and their essential versions) of Hadamard (Schur) geometric means of bounded sets of pos…

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…
