+# Contributions
+
+* We introduce a type system able to express predicated types, a unified way to
+  express existance of method- and traits depending on some predicate on the
+  subtyping relation.
+* We define our subtyping relation as a natural extension to type systems based
+  on semantic subtyping.
+* We express our subtyping using a novel approach based on the sequent calculus.
+* We show the correctness of our subtyping relation and type system.
+* We explain how this type system may be used to succinctly describe programs
+  involving for example capabilities and constructions such as type classes.
+* We have implemented the type system and give examples of how its use
+  simplifies expressing many properties in object oriented languages, including
+  things like...
