Title: Character and tightness are discretely reflexive in compact spaces.

Abstract: We will show that tightness, character, sequentiality, and Frechet-Urysohn property are discretely reflexive in compact spaces, i.e., if $X$ is a compact space in which the closure of every discrete subset has a property $P$ from the list  $tightness \leq \kappa, character\leq\kappa, sequentiality, Frechet-Urysohn property$, then $X$ has the property $P$.
