A chain map inducing isomorphisms on homology is called a quasi- isomorphism a and b are quasi-isomorphic if there exists a quasi-isomorphism between them.

The symplectic isotopy problem is a question about automorphisms of a compact symplectic manifold.
In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa. A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure. Evolutionary biology explains homologous structures adapted to different purposes as the result.
That categories enriched in cubical sets provide a convenient way to describe many infinity-categories appearing in the context of homological algebra.
The distribution character and the composition of hydrocarbons in azerbaijani oils of different types were studied. Concentrates of aromatic hydrocarbons were isolated from the 50° fractions of crude oils and oil residues boiling above 450°c. The structural-group composition of the isolated aromatic hydrocarbons was studied by spectral methods (mass spectrometry and 1h nmr spectroscopy).

The development of homological algebra was closely intertwined with the emergence of category theory. By and large, homological algebra is the study of homological functors and the intricate algebraic structures that they entail.

I am having trouble understanding the composition of morphisms in the quotient category of an abelian category, following gabriel's thesis on abelian categories.
The composition operation is bilinear and distributes over addition. Every monomorphism is the kernel of some morphism, and every epimorphism is the cokernel of some morphism. Today, we are going to look at -valued presheaves of categories.
Let a,b,c be three abelian categories, f:a→b, g:b→c be two additive.
We approach homological stability using the machinery of representation stability in the sense of church and farb in particular, we use wilson’s extension of this theory to the classical sequences of weyl groups. Each of our homological stability results is obtained by first proving representation stability for an associated sequence.
The chain complex is the central notion of homological algebra. It is a sequence of abelian groups and group homomorphisms, with the property that the composition of any two consecutive maps is zero: the elements of cn are called n-chains and the homomorphisms dn are called the boundary maps or differentials.
We are now ready to prove that defines a homological -functor. We verify the two requirements from the definition of a homological -functor. The first one states that for every short exact sequence we need to define connection morphisms such that.

The amino acid compositions of many of the known sequenced proteins were compared to determine if a relationship exists between the amino acid.
The chain complex is the central notion of homological algebra. It is a sequence of abelian groups and group homomorphisms, with the property that the composition of any two consecutive maps is zero: the elements of c n are called n-chains and the homomorphisms d n are called the boundary maps or differentials.
We propose here a study of ocysemiexactoco and ocyhomological' categories as a basis for a generalised homological algebra. Our aim is to extend the homological notions to deeply non-abelian situations, where satellites and spectral sequences can still be studied. This is a sequel of a book on ocyhomological algebra, the interplay of homology with distributive lattices and orthodox.
Mccarthy's theory enjoys a number of desirable properties, the most basic being the ugreemrnt property.

In homological and noncommutative algebra sarah witherspoon group actions are ubiquitous in mathematics. To understand a mathematical object, it is often helpful to understand its symmetries as expressed by a group. For example, a group acts on a ring by automorphisms (preserving its structure).
Homological algebra is the branch of mathematics that studies homology in a general algebraic setting.
The purpose of this paper is to give an introduction to the homological theory of comodules over coalgebras and hopf algebras.

In mathematics, homology is a general way of associating a sequence of algebraic objects, such as abelian groups or modules, to other mathematical objects.
I had a few questions about compositions of derived functors, the comparison between hypercohomology, and sheaf cohomology and the following theorem from the gelfand, manin homological algebra book: theorem (methods of homological algebra.
Homology theory can be said to start with the euler polyhedron formula, or euler characteristic. This was followed by riemann's definition of genus and n-fold connectedness numerical invariants in 1857 and betti's proof in 1871 of the independence of homology numbers from the choice of basis.
By lifting from complexes of sim- plices to algebraic complexes of vector spaces, we pass to homology as a topolog- ical compression scheme.
When this book was written, methods of algebraic topology had caused revolutions in the world of pure algebra. To clarify the advances that had been made, cartan and eilenberg tried to unify the fields and to construct the framework of a fully fledged theory.
What do quantum physics, cosmology, biology and psychology have in common? they’re all driven by information. But how can we come to agree about philosophy if we all use a different psychology to experience the world?.
