我们研究了一个上同调值超几何级数,它自然地出现在(局部)镜像对称性的描述中。我们将它确定为BPS态的中心电荷公式,并从Kontsevich的同调镜像对称性的角度研究了它的单向性。在局部镜像对称的情况下,我们将确定一个辛形式,并猜想相关的Gel‘fand-Kapranov-Zlevinsky型超几何级数的一个积分和辛单调性质。
We study a cohomology-valued hypergeometric series which naturally arises in the description of (local) mirror symmetry. We identify it as a central charge formula for BPS states and study its monodromy property from the viewpoint of Kontsevich's homological mirror symmetry. In the case of local mirror symmetry, we will identify a symplectic form, and will conjecture an integral and symplectic monodromy property of a relevant hypergeometric series of Gel'fand-Kapranov-Zelevinski type.
