Convolution Algebraic Structures Defined by Hardy-Type Operators by Pedro J. Miana, Juan J. Royo, Luis Sánchez-Lajusticia

“…The main aim of this paper is to show that certain Banach spaces, defined via integral kernel operators, are Banach modules (with respect to some known Banach algebras and convolution products on ℝ+). To do this, we consider some suitable kernels such that the Hardy-type operator is bounded in weighted Lebesgue spaces Lωpℝ+ for p≥1. …”

Invertibility-preserving maps of C∗-algebras with real rank zero by Istvan Kovacs

“…In this paper, we show that if A and B are semisimple Banach algebras and Φ:A→B is a linear map onto B that preserves the spectrum of elements, then Φ is a Jordan isomorphism if either A or B is a C∗-algebra of real rank zero. …”

BPS states, conserved charges and centres of symmetric group algebras by Garreth Kemp, Sanjaye Ramgoolam

“…Using Schur-Weyl duality relations between unitary groups and symmetric groups, these questions translate into structural questions about the centres of symmetric group algebras. We obtain algebraic and computational results about these structural properties and related Shannon entropies, and generate associated number sequences. …”
