Mimetic scalar products of discrete differential forms

We propose a strategy for the systematic construction of the mimetic inner products on cochain spaces for the numerical approximation of partial differential equations on unstructured polygonal and polyhedral meshes. The mimetic inner products are locally ...

Lq,p-cohomology of Riemannian manifolds and simplicial complexes of bounded geometry

Stephen Ducret

The Lq,p-cohomology of a Riemannian manifold (M, g) is defined to be the quotient of closed Lp-forms, modulo the exact forms which are derivatives of Lq-forms, where the measure considered comes from the Riemannian structure. The Lq,p-cohomology of a simpl ...

The classification of torsion endo-trivial modules

Jacques Thévenaz

The main purpose of this paper is to show that, if G is a finite p-group which is not cyclic, quaternion or semi-dihedral, then the group of endo-trivial G-modules is detected on restriction to elementary abelian p-subgroups of rank 2. Consequently, the to ...

Une dégustation topologique: homotopy theory in the Swiss Alps : Proceedings of the Arolla conference on algebraic topology, Arolla, Switzerland, August 25-September 1, 1999.

The talks given at the Arolla Conference on Algebraic Topology covered a broad spectrum of current research in homotopy theory, offering participants the possibility to sample and relish selected morsels of homotopy theory, much as a participant in a wine ...

Edge Elements and Cochain-Based Field Function Approximation

Claudio Mattiussi

Edge Elements (EE) have received in recent times much attention from the Finite Element community. The present contribution analyzes the role played by EE in the preservation of the fundamental prop-erties of physical equations submitted to discretization. ...
