Alpha-shapes and flow shapes are homotopy equivalent
In this paper we establish a topological similarity between two apparently different shape constructors from a set of points. Shape constructors are geometric structures that tran...

Bulking II: Classifications of Cellular Automata
This paper is the second part of a series of two papers dealing with bulking: a way to define quasi-order on cellular automata by comparing space-time diagrams up to rescaling. In...

A finiteness structure on resource terms
In our paper "Uniformity and the Taylor expansion of ordinary lambda-terms" (with Laurent Regnier), we studied a translation of lambda-terms as infinite linear combinati...

Multiresolution Surfaces having Arbitrary Topologies by a Reverse Doo Subdivision Method
We have shown how to construct multiresolution structures for reversing subdivision rules using global least squares models 16. As a result, semiorthogonal wavelet systems have al...

The algebra of connectors: structuring interaction in BIP
We provide an algebraic formalisation of connectors in BIP. These are used to structure interactions in a component-based system. A connector relates a set of typed ports. Types a...
