Twenty years ago, modal and mixed specifications were proposed as abstract models of system behavior. In this paper, we explain the nature and utility of such specifications, relate them to other formalisms, showcase some of their established applications, and mention some existing tool support. We also present some recent complexity results for decision problems underlying such applications an...

The design of efficient algorithms for planar graphs, as a field of research, is over forty year old and continues to be an exciting area. There are several new efficient algorithms for a variety of graph optimization problems that exploit planarity and, in general, the structure of low genus graphs and graphs with excluded minors. Efficient space-bounded computations, on the other hand, involv...

1 3 N ov 2 00 1 Finite order formulation of Vinogradov ’ s C - spectral sequence

The C-spectral sequence was introduced by Vinogradov in the late Seventies as a fundamental tool for the study of algebro-geometric properties of jet spaces and differential equations. A spectral sequence arise from the contact filtration of the modules of forms on jet spaces of a fibring (or on a differential equation). In order to avoid serious technical difficulties, the order of the jet spa...

Ratio m(c)/m(s) with Wilson fermions.

We determine the quark mass ratio m(c)/m(s) on the lattice, using Wilson-type fermions. Configurations with N(f)=2 dynamical clover-improved fermions by the QCDSF Collaboration are used, which were made available through the ILDG. In the valence sector we use a sophisticated, mass-independently O(a)-improved Wilson-type action with small cutoff effects even in the charm mass region. After an ex...
