真正的无分散Veselov-Novikov层次结构的解决方案

Solutions for real dispersionless Veselov-Novikov hierarchy

Jen-Hsu Chang, Yu-Tung Chen

摘要:

在无色散双分量BKP族框架下研究了无色散Veselov-Novikov(dVN)方程.考虑了实际dVN系统的对称性约束。结果表明,对称性减少下,保守的密度,因此相关的Faber多项式,可以递归地解决。此外,速度图变换的方法以及Faber多项式的表达式被用来找到dVN族的精确实解。

英文摘要:

We investigate the dispersionless Veselov-Novikov (dVN) equation based on the framework of dispersionless two-component BKP hierarchy. Symmetry constraints for real dVN system are considered. It is shown that under symmetry reductions, the conserved densities are therefore related to the associated Faber polynomials and can be solved recursively. Moreover, the method of hodograph transformation as well as the expressions of Faber polynomials are used to find exact real solutions of the dVN hierarchy.
