超引力BPS方程的可积系统

Integrable systems from supergravity BPS equations

Eric D'Hoker, John Estes

摘要:

Sine-Gordon/Liouville型的可积系统是由IIB型超引力和M理论中16种超对称下不变解的BPS方程约化而成的,它是由实变量的任意实函数$f$参数化的可积系统的无限族的特例.证明了对于每个函数$f$,这个广义可积系统可以映射到一个线性方程组上,而线性方程组又可以用一个只依赖于函数$f$的二阶常线性微分方程的两个线性无关解来积分.

英文摘要:

Integrable systems of the sine-Gordon/Liouville type, which arise from reducing the BPS equations for solutions invariant under 16 supersymmetries in Type IIB supergravity and M-theory, are shown to be special cases of an infinite family of integrable systems, parametrized by an arbitrary real function $f$ of a real variable. It is shown that, for each function $f$, this generalized integrable system may be mapped onto a system of linear equations, which in turn may be integrated in terms of the two linearly independent solutions of an ordinary linear second order differential equation which depends only on the function $f$.
