We present a type theory with some proof-irrelevance built into the conversion rule. We argue that this feature is useful when type theory is used as the logical formalism underlyi...
The goal of the paper is to explicate some common formal logic underlying various notational systems used in visual modeling. The idea is to treat the notational diversity as the d...

One of the central aspects in an Information System is the meaning of data in the external world and the information carried by them. We propose a Constructive Object Oriented Mod...

The paper reports on the foundations and experimental results with a model checker for component connectors modelled by networks of channels in the calculus Reo. The specificatio...
We formalise natural deduction for first-order logic in the proof assistant Coq, using De Bruijn indices for variable binding. The main judgement we model is of the form d [:] , ...
