Homology of systemic modules

چکیده
In this paper, we develop the rudiments of a tropical homology theory. We use language “triples” and “systems” to simultaneously treat structures from various approaches mathematics, including semirings, hyperfields, super algebra. enrich algebraic with negation map where it does not exist naturally. obtain an analogue Schanuel’s lemma which allows us talk about projective dimension modules in setting. define two different versions exactness, study their properties. also prove weak Snake type result.

We investigate the relative cohomology and relative homology theories of $F$-Gorenstein modules, consider the relations between classical and $F$-Gorenstein (co)homology theories.
متن کاملGeneralized 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 ...
متن کاملON THE VANISHING OF DERIVED LOCAL HOMOLOGY MODULES
Let $R$ be a commutative Noetherian ring, $fa$ anideal of $R$ and $mathcal{D}(R)$ denote the derived category of$R$-modules. For any homologically bounded complex $X$, we conjecture that$sup {bf L}Lambda^{fa}(X)leq$ mag$_RX$. We prove thisin several cases. This generalize the main result of Hatamkhani and Divaani-Aazar cite{HD} for complexes.
