dc.description.abstractUniverse types characterise aliasing in object oriented programming languages and are used to reason modularly about programs. In this report we formalise prior work by M ̈uller and Poetzsch-Heffter, who designed the Universe Type System for a core subset of Java. We present our work in two steps. We first give a Topological Universe Type System and show subject reduction to a small-step dynamic semantics for our language. Motivated by concerns of Modular verification, we then give an Encapsulation Universe Type System (based on the owner-as-modifier principle), prove subject reduction with respect to the former small-step semantics, and show how the type system can be used for modular verification.en_GB
