%0 Journal Article %T Topological extensions with compact remainder %A M. R. Koushesh %J Mathematics %D 2015 %I arXiv %X Let $\mathfrak{P}$ be a topological property. We study the relation between the order structure of the set of all $\mathfrak{P}$-extensions of a completely regular space $X$ with compact remainder (partially ordered by the standard partial order $\leq$) and the topology of certain subspaces of the outgrowth $\beta X\setminus X$. The cases when $\mathfrak{P}$ is either pseudocompactness or realcompactness are studied in more detail. %U http://arxiv.org/abs/1502.04556v1
