cohomology algebra 中文意思是什麼
-
Especially, we compute the hochschild cohomology of endomorphism algebras of complete exceptional sequence of the path algebra whose quiver has 3 vertices and has no orientation
第四章中，我們主要研究具有三個點的且不帶方向圈的有向箭圖的路代數上的完備例外序列的自同態代數的hochschild上同調群。 -
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 graded lie algebra of cartan type
型李代數的上同調 -
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。 -
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。 -
The main conclusion is as follows : for i > 2, the hochschild homology hi ( a ) of an algebra a is equal to the the hochschild homology hi ( b ) of the algebra b where b = a / j and j is a heredity ideal of a. c. cibils studied the hochschild cohomology of split algebras with bicom - plexs
本文中，我們首先就一類特殊的同調理想-遺傳理想j進行了研究，給出了a和b在次數大於1時其hochschild同調相等的證明，對于其一次和0次hochschild同調可用一個正合列聯系它們。
