Duals of Tirilman spaces have unique subsymmetric basic sequences
The Tirilman spaces $Ti(p,γ)$, $1<p<\infty$, 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 $Ti^*(p,γ)$ are equivalent to its canonical subsymmetic but not symmetric basis.
