通过复曲线和生成微分,构造了扩展的户田链族的准经典解,它对应于对偶拓扑弦模型的所有后代对最简单的Seiberg-Witten理论的变形.将户田链推广到预势或准经典τ函数的额外时间上,得到了其一阶导数的Seiberg-Witten单形式的重积分表达式.我们推导出相应的拟经典Virasoro约束,讨论的功能制定的问题,并提出推广的扩展户田层次的nonabel理论。
The quasiclassical solution to the extended Toda chain hierarchy, corresponding to the deformation of the simplest Seiberg-Witten theory by all descendants of the dual topological string model, is constructed explicitly in terms of the complex curve and generating differential. The first derivatives of prepotential or quasiclassical tau-function over the extra times, extending the Toda chain, are expressed through the multiple integrals of the Seiberg-Witten one-form. We derive the corresponding quasiclassical Virasoro constraints, discuss the functional formulation of the problem and propose generalization of the extended Toda hierarchy to the nonabelian theory.
