  1. 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。
  2. 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。
