A solution to Michael's problem for Fréchet algebras
Antonio Acuaviva
We prove that every character on a commutative complex complete Hausdorff locally multiplicatively convex algebra, not necessarily unital, is bounded on bounded sets. Consequently,…

On complemented subspaces of
Antonio Acuaviva
We construct two complemented subspaces of . The first has the Schur property but fails the Radon--Nikodým property. The second contains a copy of but no copy of…

State Transfer in Complex Quantum Walks
Antonio Acuaviva, Ada Chan, Summer Eldridge +5
Given a graph with Hermitian adjacency matrix , perfect state transfer occurs from vertex to vertex if the -entry of the unitary matrix has unit magn…
