Duals of Tirilman spaces have unique subsymmetric basic sequences

Functional Analysis 2024-02-21 v1

Abstract

The Tirilman spaces Ti(p,γ)Ti(p,\gamma), 1<p<1<p<\infty, were introduced by Casazza and Shura as variations of the spaces constructed by Tzafriri. We prove that all subsymmetric basic sequences in the dual space Ti(p,γ)Ti^*(p,\gamma) are equivalent to its canonical subsymmetic but not symmetric basis.
