Computation of Homology Groups and Generators [PDF]
Computers & Graphics, 2005 Topological invariants are extremely useful in many applications related to digital imaging and geometric modeling, and homology is a classical one, which has not yet been fully explored in image applications. We present an algorithm that computes the whole homology of an object of arbitrary dimension: Betti numbers, torsion coefficients and generators.

Моделирование и анализ информационных систем, 2013 We study homology groups of the space W˜₁(∇N ) of triangulations of the twodimensional simplex with vertices D₀D₁D₂ endowed with a boundary subdivision with not more than 6 vertices in case when this boundary subdivision is extended to the interior of ...

FREE FINITE GROUP ACTIONS ON RATIONAL HOMOLOGY 3-SPHERES
Forum of Mathematics, Sigma, 2019 We use methods from the cohomology of groups to describe the finite groups which can act freely and homologically trivially on closed 3-manifolds which are rational homology spheres.

New Proposal of Setal Homology in Schizomida and Revision of Surazomus (Hubbardiidae) from Ecuador. [PDF]
PLoS ONE, 2016 The homology of three somatic systems in Schizomida is studied yielding the following results: (1) proposal of homology and chaetotaxy of abdominal setae in Surazomus; (2) revision of the cheliceral chaetotaxy in Schizomida, with suggestion of new ...

Knot concordance and homology sphere groups [PDF]
, 2017 We study two homomorphisms to the rational homology sphere group. If $\psi$ denotes the inclusion homomorphism from the integral homology sphere group, then using work of Lisca we show that the image of $\psi$ intersects trivially with the subgroup of ...

A Spatiotemporal Brain Network Analysis of Alzheimer’s Disease Based on Persistent Homology
Frontiers in Aging Neuroscience, 2022 Current brain network studies based on persistent homology mainly focus on the spatial evolution over multiple spatial scales, and there is little research on the evolution of a spatiotemporal brain network of Alzheimer’s disease (AD).

F1000Research, 2022 Background: In autoimmune vasculitis, autoantibodies to Human Proteinase 3 (PR3), a human serine protease, seems to have a role on the inception of c-ANCA associated vasculitis. The origin of this autoreactive response remains unclear.

Homology in Varieties of Groups. III [PDF]
Transactions of the American Mathematical Society, 1971 The study of (co-) homology groups Z,3(HX A), SnI3(H, A), 3 a variety, 11 a group in 3, and A a suitable 11-module, is pursued. They are compared with a certain Tor and Ext. The definition of the homology of an epimorphism due to Rinehart is shown to agree with that due to Barr and Beck (whenever both are defined).
