Spectrum-generating超代数的一类子代数的研究

摘要

研究spectrum-generating超代数的一类子代数，确定了这类子代数的低阶上同调群以及自同构群。这类子代数对于讨论N=2-超共形代数上Harish-Chandea模的分类很有意义。%　　One subalgebra of spectrum-generating superalgebra is studied in this paper. And low order cohomol⁃ogy group and the automorphism group of this algebra are also determined in the paper. This subalgebra is help⁃ful to classified Harish-Chandea modules over the N =2 superconformal algebra.
