The double scaling limit method in the Toda hierarchy

L. Martinez Alonso, E. Medina

摘要:

考虑了色散Toda族解的半经典展开式的临界点,给出了正则化的双标度极限方法。分析了厄米矩阵模型中由强条件表征的临界点的相似性,证明了方程组的加倍性。本文引入了一族广泛的临界点集,并讨论了相应的双标度极限展开式。

英文摘要:

Critical points of semiclassical expansions of solutions to the dispersionful Toda hierarchy are considered and a double scaling limit method of regularization is formulated. The analogues of the critical points characterized by the strong conditions in the Hermitian matrix model are analyzed and the property of doubling of equations is proved. A wide family of sets of critical points is introduced and the corresponding double scaling limit expansions are discussed.
