# Topic: Snake lemma

###### In the News (Tue 21 May 13)

 PlanetMath: snake lemma, proof of This proof was reconstructed without any notes, but the style of the proof is influenced by a presentation by Edgar Enochs of the zig-zag lemma. "proof of snake lemma" is owned by mps. This is version 1 of proof of snake lemma, born on 2004-02-14. www.planetmath.org /encyclopedia/ProofOfSnakeLemma.html   (244 words)

 Kids.Net.Au - Encyclopedia > Snake lemma In mathematics, especially homological algebra and other applications of Abelian category theory, the snake lemma is a basic tool used in diagram chasing[?]. The maps between the kernels and the maps between the cokernels are induced in a natural manner given the exactness of the rows; the important statement of the lemma is that a connecting homomorphism d exists which completes the exact sequence. The snake lemma is the crucial tool to construct the long exact sequences of homological algebra. www.kids.net.au /encyclopedia-wiki/sn/Snake_lemma   (235 words)

 MathFiction: It's My Turn (Claudia Weill (director)) About a mathematician who writes a proof of the Snake Lemma at the speed of light. "Given that Clayburgh was going to prove the "snake lemma", why the hell didn't she generalize slightly and derive the long homology exact sequence associated to a short exact sequence of chain complexes? By the way, as it happens, when I saw this film some 21 years ago, I had, just the day before, lectured on the homology exact sequence in an intro algebraic topology course. math.cofc.edu /faculty/kasman/MATHFICT/mfview.php?callnumber=mf32   (496 words)
