In this paper we introduce a new approach to formalizing certain type operations in type theory. Traditionally, many type constructors in type theory are independently axiomatized...

We present direct proofs of termination of evaluation for typed delimited-control operators shift and reset using a variant of Tait’s method with context-based reducibility pred...

Semantics represents a major problem area for active databases inasmuch as (i) there is l framework for defining the abstract semantics of active rules, and (ii) the various syst...
