Simplicial homology of chain complexes
Webbsimplicial complexes survives when considering nonlinear dynam-ical systems. They then identify the symmetries of the dynamics induced by the simplicial complex structure, study the effect of the simplicial complex orientation on the dynamics, and relate the sym-metries to invariant subspaces of the dynamics. The authors, thus, Webbhomology theory, applying equally well to Khovanov Homology and to Knot Floer Homology and other theories of these types. A simplifyingpoint in producinga …

WebbIn this paper, we present several algorithms related with the computation of the homology of groups, from a geometric perspective (that is to say, carrying out the calculations by means of simplicial sets and using techniques of Algebraic Topology). ... WebbIn the case of smooth manifolds, we use Forman’s discrete Morse theory to realize combinatorially any Thom-Smale complex coming from a smooth Morse function by a couple triangulation-discrete Morse function. As an application, we prove that any Euler structure on a smooth oriented closed 3-manifold has a particular realization by a …
