sl_2-模W(m,2,t)的零维上同调

The Zero Dimensional Cohomology of sl_2-module in W(m,2,t)

对W(m,2,t)做了6个sl2-子模的直和分解,而且每个直和项又可分解为不可约sl2子模的直和,并且通过计算给出了sl2-模W(m,2,t)的零维上同调群.

The W（m,2,t） is a sl2-module,and it can be broken down into 6 submodules.The zero dimensional cohomology groups of-with coefficient in W（m,2,t） is calculated.
