An application of Hochschild cohomology to the moduli of subalgebras of the full matrix ring II (Q4959698)

The motivation of the authors is the construction of moduli group representations which have the same type and also to understand subalgebras of the full matrix ring. First, the authors review Hochschild cohomology and the moduli of molds. Then they introduce several applications of Hochschild cohomology and describe the moduli of molds. By using \textit{C. Cibils}'s results [J. Pure Appl. Algebra 56, No. 3, 221--232 (1989; Zbl 0683.16018)], they obtain calculations of Hochschild cohomology groups in several cases.
