Every topological space gives rise to a pseudotopological spacepseudotopological space. Conversely, if $X$ is a pseudotopological space then we can define a topology on $X$ such that every filter converging to $x$ in the original pseudotopology also converges in this topology.
Let $(X,T)$ be a topological space. Let $F$ a subspace of $(X,T)$ considered as a pseudotopological space. My question is that whether $F$ necessarily is a subspace of the topological space $(X,T)$ or not.
