Subtyping relations for the -calculus are usually defined in a syntactic way, by means of structural rules. We propose a semantic characterisation of channel types and use it to d...

Subtyping rules can be fairly complex for union types, due to interactions with other types, such as function types. Furthermore, these interactions turn out to depend on the calc...
Abstract: Subtyping and inheritance are two major issues in the research and development of object-oriented languages, which have been traditionally studied along the lines of type...
Abstract. We propose a new type discipline for the -calculus in which secure information flow is guaranteed by static type checking. Secrecy levels are assigned to channels and are...
XML data is often used (validated, stored, queried, etc) with respect to di erent types. Understanding the relationship between these types can provide important information for ma...
