We propose union types for statically typed class-based objectoriented languages as a means to enhance the flexibility of subtyping. As its name suggests, a union type can be con...
We present a multi-lingual type inference system for checking type safety of programs that use the Java Native Interface (JNI). The JNI uses specially-formatted strings to represe...
Partial types allow the reasoning about partial functions in type theory. The partial functions of main interest are recursively computed functions, which are commonly assigned ty...
