Homology evolving

over 150 years, with different meanings over time for different groups of biologists. Although first used to describe ‘the same organ under every variety of form and function’, most biologists now use homology to denote hypotheses of evolutionary relationship among traits of organisms. This is justified by the fact that darwinian evolution has replaced FIDELITY TO ARCHETYPE as the explanation f...

Relative (co)homology of $F$-Gorenstein modules

We investigate the relative cohomology and relative homology theories of $F$-Gorenstein modules, consider the relations between classical and $F$-Gorenstein (co)homology theories.

Exact sequences of extended $d$-homology

In this article, we show the existence of certain exact sequences with respect to two homology theories, called d-homology and extended d-homology. We present sufficient conditions for the existence of long exact extended d- homology sequence. Also we give some illustrative examples.

Generalized Local Homology Modules of Complexes

The theory of local homology modules was initiated by Matlis in 1974. It is a dual version of the theory of local cohomology modules. Mohammadi and Divaani-Aazar (2012) studied the connection between local homology and Gorenstein flat modules by using Gorenstein flat resolutions. In this paper, we introduce generalized local homology modules for complexes and we give several ways for computing ...
