Islands in Closed and Open Universes

Recent work established necessary conditions for so-called "entanglement islands" to appear in flat cosmological universes. After reviewing the motivation for and definition of entanglement islands, I will examine the effects of spatial curvature on the existence of islands in cosmological settings. Along the way, I will discuss a new necessary condition for proper subsets of closed universes to be islands. I will then examine if and when the conditions for islands are satisfied and compare the results to those in flat cosmologies.
