Abstract

This report deals with a type system that merges subtyping and dependent types. We define a calculus that instead of term overloading employs coercion mappings. This enables to detach the subtyping from other parts of the calculus, so that the mutual dependence between subtyping, typing and kinding can be reduced. We analyze basic properties of the calculus and show several examples that demonstrate the mechanism of coercive subtyping.
