Talk:Homological algebra

Unorthodox definition of singular homology?
The text states "if $$X$$ is a topological space then the singular chains $$C_n(X)$$ are formal linear combinations of continuous maps from the $$n$$-sphere into $$X$$". The more common definition is based on maps from the topological $$n$$-simplex into $$X$$, equivalently, from the closed $$n$$-ball into $$X$$. June 7-th 2008

New To Advanced Math
Hi; I'm trying desperately to understand many of these advanced principals of mathematics, such as hmological algebra, but no matter how many times I review the material, it doesn't sink in. Could someone please provide examples, problems to solve (with their solutions) and/or ways to visualize this? beno 26 Jan 2006


 * How much math have you studied? At a minimum you should know the basic properties of groups, rings, fields, and modules from abstract algebra, along with the basic fundaments of algebraic topology. I suppose chain complexes would be a concrete place to start. Learning all of this stuff typically takes years of study. - Gauge 07:26, 28 January 2006 (UTC)
