The use of patterns in e-learning is being recently proposed with different purposes and scopes. This paper provides a unifying view of several representative proposals in order t...
We present a type system extending the dependent type theory LF, whose terms are more amenable to compact representation. This is achieved by carefully omitting certain subterms w...
The contribution of the paper is twofold. First, we define a general notion of type system equipped with an entailment relation between type environments; this generalisation serv...
We present a new predicative and decidable type system, called ML , suitable for languages that integrate functional programming and parametric polymorphism in the tradition of ML...
Abstract. For discrete-time linear systems over a principal ideal domain, three types of (C, A)invariance can be distinguished. Connections between these notions are investigated. ...
