On the inclusion relations between Gelfand-Shilov spaces

Functional Analysis 2025-10-07 v2

Abstract

We study inclusion relations between Gelfand-Shilov type spaces defined via a weight (multi-)sequence system, a weight function system, and a translation-invariant Banach function space. We characterize when such spaces are included into one another in terms of growth relations for the defining weight sequence and function systems. Our general framework allows for a unified treatment of the Gelfand-Shilov spaces S[A][M]\mathcal{S}^{[M]}_{[A]} (defined via weight sequences MM and AA) and the Beurling-Bj\"orck spaces S[η][ω]\mathcal{S}^{[\omega]}_{[\eta]} (defined via weight functions ω\omega and η\eta).
