Substructuring Preconditioners for Mortar Discretization of a Degenerate Evolution Problem
In this paper we present new efficient variants of structured preconditioners for algebraic linear systems arising from the mortar discretization of a degenerate parabolic system o...

The Persistent Morse Complex Segmentation of a 3-Manifold
We describe an algorithm for segmenting three-dimensional medical imaging data modeled as a continuous function on a 3-manifold. It is related to watershed algorithms developed in ...

Exception Handling and Term Labelling
: We propose a new algebraic framework for exception handling which is powerful enough to cope with many exception handling features such that recovery, implicit propagation of exc...

Synchronous + Concurrent + Sequential = Earlier than + Not later than
In this paper, we show how to obtain causal semantics distinguishing ”earlier than” and ”not later than” causality between events from algebraic semantics of Petri nets. J...
