WebTheorem 4.2.3 implies that the connecting homomorphism in the long exact se-quence (3.3.1) is surjective (Theorem 6.2.1). We compute Hochschild cohomology with trivial coefficients (Theorem 6.1.4) and apply the connecting homomorphism to give the degree two bialgebra cohomology in Theorem 6.2.7. This computation WebTheorem2.6below, which gives a description of the connecting homomorphism @ when we cannot prove it zero by the oriented method. This is the part where the non-oriented behavior really appears. See more in Remark2.7. Main Theorem2.6 is especially striking since the original de nition of the connecting homomorphism

The snake lemma is valid in every abelian category and is a crucial tool in homological … See more The maps between the kernels and the maps between the cokernels are induced in a natural manner by the given (horizontal) maps because of the diagram's commutativity. The exactness of the two induced sequences follows in a straightforward way … See more While many results of homological algebra, such as the five lemma or the nine lemma, hold for abelian categories as well as in the category of groups, the snake lemma does not. Indeed, arbitrary cokernels do not exist.
