摘要 主要在对代数上的模范畴研究的基础上,开展余代数的余模范畴的研究对讨论余代数的结构与表示有重要意义.根据Hochschild上同调群的理论,研究有向图的无穷小余代数、有限域的Hochschild上同调群的计算. Based on the study of module categories over algebra,the study of comodule categories over coalgebra is important to discuss the structure and representation of coalgebra.According to the cohomology group theories,the calculation of Hochschild cohomology groups over digraph infinitesimal coalgebra and a finite field are studied.
