is a commutative diagram with exact rows, then the snake lemma can be applied twice, to the "front" and to the "back", yielding two long exact sequences; these are related by a commutative diagram of the form In popular culture The proof of the snake lemma is being taught by Jill Clayburgh at the very beginning of the 1980 film It's My Turn.

For c2ker() let s(c) = a0+im( ) 2cok( ), where g(b) = c and f 0(a) = (b). Then ker( ) !f ker( ) !g ker() !s cok( ) f 0! cok( ) g 0! cok() is exact. Snake lemma demonstration from the 1980's film, It's My Turn, starring Jill Clayburgh and Michael Douglas.

A lecture on the Snake lemma in homological algebra in which a student pretends to know things better. 2021-03-26 The proof is completed. B.3 Proof of Theorem 3 To prove theorem 3, we rst establish a lemma on ow decomposition, and then accomplish the proof based on the lemma. B.3.1 A Lemma on Flow Decomposition For the joint chain P +, we analyze its bottleneck ratio by decomposing the ows. Consider a partition of the union space X[Y into two parts: A[B The Snake Lemma Most graduate students in mathematics will be asked to prove the snake lemma at least once (if not multiple times) over the course of their studies. It is ex-tremely diﬃcult to ﬁnd a complete proof that does not skip steps or simply instruct the reader to complete parts of the proof as an exercise.

Actually, I have the impression that I use nowhere the commutativity of the diagram. Actually, this is the diagram I consider : ( w) → c o k e r ( u) . ( w).

Particularly if you have an exact (anti)-commutative diagram. you get an exact sequence. We also have a little write-up of the proof here. The snake lemma, and the long exact sequence in (co-) homology, has an interesting application to some very small complexes, which appear in the proof of the following. [2.0.1] Proposition: Let A, B, Cbe R-modules over a (not necessarily commutative) C-algebra R. This is a particularly fun and relaxing method of proof, since it is basically impossible to go wrong (i.e. if the proof doesn't work, the theorem is false.) Fun fact: After a hard day's work, many mathematicians like to open up the fridge, grab a beer, then kick back and chill on the sofa while diagram chasing. 🤓 Buyer’s Guide: Best Hiking Snake Proof Chaps (2021) Before venturing on expeditions in a snake-laden area, it is better to be fully shielded to avoid any painful experience.
