The relationship of simple connectedness and 1 hochschild cohomology group is very clear for representation - finite algebras
單連通性和一次hochschild上同調群之間的聯系，在有限表示型的情形已經很清楚了。 -
By using two kinds of affine representations of lie color algebras and the first cohomology group, we obtain some necessary or sufficient conditions to the problem whether there is any left color sysmmetric structure on a given lie color algebra which generalize the result of [ 2 ]
利用著色李超代數的兩種仿射表示和1 -上同調群，得出左著色對稱結構存在的幾個充分或必要條件，推廣了文[ 2 ]的結論。 -
Cohomology of a group
群的上同調 -
E for an algebra of minimal representation - infinite type with preprojective component, it is simply connected if and only if the vanishing of 1 hochschild cohomology group ; the same conclusion is true for a general algebra with minimal representation - infinite type. in chapter 3, we computed the fundamental group for hereditary algebra and other special cases, and studied the fundamental group under one point extension
在第二章中我們得到了極小無限表示型代數單連通性的一些結論：對于具有預投射分支的極小無限表示型代數，它是單連通當且僅當其一次hochschild上同調群為零；而對於一般情形的極小無限表示型代數，也是如此。第三章中，我們對基本群在遺傳代數等幾種特殊情況下，對於一些例子作了計算。 -
Singular cohomology group
奇異上同調群 -
Lower degree hochschild cohomology group have a very concrete interpretation of classic algebraic structure, especially, there are inner connection between 1 hochschild cohomology group and simply connected algebra
低次的hochschild上同調群對于典型的代數的結構有具體的解釋，尤其是一次的hochschild上同調群與單連通代數有著內在的聯系。
