Since c is an arbitrary element of Ker(γ) (the domain of δ), then cα δ is the zero function and Im(δ) ⊂ Ker(cα). Conversely, suppose a0 + Im(α) ∈ A0/Im(α) = Coker(α) is in the kernel of cα. Then The snake lemma is a tool used in mathematics, particularly homological algebra, to construct long exact sequences. The snake lemma is valid in every abelian category and is a crucial tool in homological algebra and its applications, for instance in algebraic topology. Homomorphisms constructed with its help are generally called connecting homomorphisms. Actually I believe that there is a "unique" way to prove the Snake lemma, and the commutativity is used for the well-definedness of the "boundary" map $M_3\to N_1$.

snake lemma ⇒ \Rightarrow connecting homomorphism Example: Snake Lemma Published 2012-11-18 | Author: Andrew Stacey This example uses the tikz-cd package because of the “asymmetrical rectangle” node style, and it loads the matrix and calc libraries for cleaner code. The snake lemma doesn't make sense in the category of groups in general, because maps don't always have cokernels.

The purpose of this paper is to prove a new, incomplete-relative, version of Non-abelian Snake Lemma, where \relative" refers to … In this talk, we will see a proof of the snake lemma. The talk will assume a basic familiarity (group homomorphisms, kernels, cokernels, etc.) with group theory. Time permitting, the speaker will also explain an application of the snake lemma to his own work.
