... fifteenth century was a thriving commercial community with a growing need, as in the Italian cities, for practical mathematics. It was probably to meet this need that Chuquet composed his Triparty (Le Triparty en la Science des Nombres par Maistre Nicolas Chuquet Parisien) in 1484, a work on arithme ...

... Assume L/K is abelian (that is, Gal(L/K) is abelian). The abelian case is what class field theory is all about. Then the decomposition groups Gal(L/K)P : P | p are all the same, so we just refer to all of them as Gal(L/K)p , the decompositon group of p. We have a homomorphism Gal(L/K)p → Gal((OL /P) ...

Homological algebra



Homological algebra is the branch of mathematics that studies homology in a general algebraic setting. It is a relatively young discipline, whose origins can be traced to investigations in combinatorial topology (a precursor to algebraic topology) and abstract algebra (theory of modules and syzygies) at the end of the 19th century, chiefly by Henri Poincaré and David Hilbert. 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. One quite useful and ubiquitous concept in mathematics is that of chain complexes, which can be studied both through their homology and cohomology. Homological algebra affords the means to extract information contained in these complexes and present it in the form of homological invariants of rings, modules, topological spaces, and other 'tangible' mathematical objects. A powerful tool for doing this is provided by spectral sequences.From its very origins, homological algebra has played an enormous role in algebraic topology. Its sphere of influence has gradually expanded and presently includes commutative algebra, algebraic geometry, algebraic number theory, representation theory, mathematical physics, operator algebras, complex analysis, and the theory of partial differential equations. K-theory is an independent discipline which draws upon methods of homological algebra, as does the noncommutative geometry of Alain Connes.
