${\Omega \choose T}\neq {\Omega \choose \Gamma}$

Abstract

We show that the selection principles ${\Omega\choose T}$ and ${\Omega\choose\Gamma}$ are not equal constructing a topological space $(X,\tau)$ that satisfies ${\Omega \choose T}$, but not ${\Omega \choose \Gamma}$. This answers a question from arXiv:math/0301011 .
