中文摘要:
      研究了系数在模李超代数~$W(m,3,\underline{1})$ 上的~$\frak{gl}(2,\mathbb{F})$ 的一维上同调, 其中~$\mathbb{F}$ 是一个素特征的代数闭域且~$\frak{gl}(2,\mathbb{F})$ 是系数在~$\mathbb{F}$ 上的~$2\times 2$ 阶矩阵李代数. 计算出所有~$\frak{gl}(2,\mathbb{F})$ 到模李超代数~$W(m,3,\underline{1})$ 的子模的导子和内导子. 从而一维上同调~$\textrm{H}^{1}(\frak{gl}(2,\mathbb{F}),W(m,3,\underline{1}))$ 可以完全用矩阵的形式表示.
英文摘要:
      The first cohomology of $\frak{gl}(2,\mathbb{F})$ with coefficients in the modular Lie superalgebra $W(m,3,\underline{1})$ is studied, where $\mathbb{F}$ is an algebraically closed field of prime characteristic and $\frak{gl}(2,\mathbb{F})$ is the Lie algebra of all $2\times 2$ matrices with entries in $\mathbb{F}$. The derivations and inner derivations from $\frak{gl}(2,\mathbb{F})$ into submodules of modular Lie superalgebra $W(m,3,\underline{1})$ are calculated. Then the first cohomology group $\textrm{H}^{1}(\frak{gl}(2,\mathbb{F}),W(m,3,\underline{1}))$ is completely determined by matrices.
