扭手征微分算子代数与$\frak{g}$ -模的仿射局部化
Algebras of twisted chiral differential operators and affine localization of $\frak{g}$-modules
摘要：
提出了第一Pontrjagin类为零的代数流形上的手征微分算子代数的概念。我们发现，这样的代数具有家庭的模块取决于无穷多个复杂的参数，我们分类在相应的代数扭曲微分算子。如果基础流形是旗流形，我们的构造恢复模的仿射李代数参数化的opers在朗兰兹对偶李代数。空间的整体瓣的“最小”这样的模块是不可约的$\ghat$ -模块和所有不可约的$\frak{g}$ -可积的$\ghat$ -模块在关键的水平出现在这种方式。
英文摘要：
We propose a notion of algebra of {\it twisted} chiral differential operators over algebraic manifolds with vanishing 1st Pontrjagin class. We show that such algebras possess families of modules depending on infinitely many complex parameters, which we classify in terms of the corresponding algebra of twisted differential operators. If the underlying manifold is a flag manifold, our construction recovers modules over an affine Lie algebra parameterized by opers over the Langlands dual Lie algebra. The spaces of global sections of "smallest" such modules are irreducible $\ghat$-modules and all irreducible $\frak{g}$-integrable $\ghat$-modules at the critical level arise in this way.
