Abstract: To construct mirror symmetric Landau-Ginzburg models, P.Berglund, T.H\"ubsch and M.Henningson considered a pair $(f,G)$ consisting of an invertible polynomial $f$ and an abelian group $G$ of...
Abstract: In this expository article, we explain how to use localization to compute Gromov-Witten invariants of smooth toric varieties and orbifold Gromov-Witten invariants of smooth toric Deligne-Mum...
Abstract: In this article, we consider permutation orbifold models of $C_2$-cofinite vertex operator algebras of CFT type. We show the $C_2$-cofiniteness of the 2-cyclic permutation orbifold model $(V...
In this paper we apply the previously derived formalism of permutation orbifold conformal field theories to N=2 supersymmetric minimal models. By interchanging extensions and permutations of the fact...
The orbifold cohomology of moduli of hyperelliptic curves     moduli  hyperelliptic curves       font style='font-size:12px;'> 2010/11/24
We study the inertia stack of [M_{0,n}/S_n], the quotient stack of the moduli stack of smooth genus 0 curves with n marked points via the action of the symmetric group S_n. Then we see how from this ...
In this article we study the period map for a family of K3 surfaces which is given by the anticanon-ial divisor of a toric variety. We determine the period di erential equation and its monodromy group...
Computations of the orbifold Yamabe invariant      Computations  orbifold Yamabe invariant        font style='font-size:12px;'> 2010/12/8
We consider the Yamabe invariant of a compact orbifold with finitely many singular points. We prove a fundamental inequality for the estimate of the invariant from above, which also includes a criteri...
In this paper we argue that the compactified Milne space is a promising model of the cosmological singularity. It is shown that extended objects like strings propagate in a well-defined manner across ...
c=3,N=2超共形场论的Z2 Orbifold–Prime模型     共形场论  orbifolD  配分函数       font style='font-size:12px;'> 2009/5/22
讨论了二维环面上中心荷c=3,N=2的超共形场论.特别给出该理论的配分函数.进一步,为了产生新的模型,回顾了一般的orbifold方法.然后构造了模不变的Z2 Orbifold Prime模型.
