G-扭曲支撑与轨道型Landau-Ginzburg模型
G-twisted braces and orbifold Landau-Ginzburg Models
摘要:
给定一个具有群$G$ -作用的代数,构造了它的$G$ -扭曲Hochschild上链的支撑结构.作为应用,我们构造了轨道Landau-Ginzburg B-模型的$G$ -Frobenius代数,并给出了所有可逆多项式的轨道上积公式.
英文摘要:
Given an algebra with group $G$-action, we construct brace structures for its $G$-twisted Hochschild cochains. An an application, we construct $G$-Frobenius algebras for orbifold Landau-Ginzburg B-models and present explicit orbifold cup product formula for all invertible polynomials.
