WDVV方程的一类新解

A new class of solutions to the WDVV equation

Olaf Lechtenfeld, Kirill Polovnikov

摘要:

Witten-Dijkgraaf-Verlinde-Verlinde(WDVV)方程的前势解F由一组余向量{alpha}参数化.由于F_{alpha oplus beta} = F_{alpha} + F_{beta},因此该集合可以被认为是不可分解的。我们通过在F的标准形式上增加所谓的径向项来耦合相互正交的余向量集。由此产生的可约共向量集产生一种新的类型的不可约解的WDVV方程。

英文摘要:

The known prepotential solutions F to the Witten-Dijkgraaf-Verlinde-Verlinde (WDVV) equation are parametrized by a set {alpha} of covectors. This set may be taken to be indecomposable, since F_{alpha oplus beta}=F_{alpha}+F_{beta}. We couple mutually orthogonal covector sets by adding so-called radial terms to the standard form of F. The resulting reducible covector set yields a new type of irreducible solution to the WDVV equation.
