Sharp Inequalities for Schur-Convex Functionals of Partial Traces over Unitary Orbits
Pablo Costa Rico, Pavel Shteyner
While many bounds have been proved for partial trace inequalities over the last decades for a large variety of quantities, recent problems in quantum information theory demand shar…

Combinatorial properties of holographic entropy inequalities
Guglielmo Grimaldi, Matthew Headrick, Veronika E. Hubeny +1
A holographic entropy inequality (HEI) is a linear inequality obeyed by Ryu-Takayanagi holographic entanglement entropies, or equivalently by the minimum cut function on weighted g…

Comparing the numbers of subforests and subgraph-degree-tuples
Sergei Shteiner, Pavel Shteyner
We enumerate the row-column-sums of all square tridiagonal -matrices and prove that their count coincides with OEIS A022026 the number of acyclic subgraphs of the comple…
