一类非线性类sigma模型的孤子

Solitons of Some Nonlinear Sigma-Like Models

V. E. Vekslerchik

摘要:

给出了一类矩阵的微分恒等式。利用这些恒等式导出了Pohlmeyer非线性σ模型、二维自对偶Yang-Mills方程和一些修正的矢量Calapso方程的$N$孤子解。

英文摘要:

We present a set of differential identities for some class of matrices. These identities are used to derive the $N$-soliton solutions for the Pohlmeyer nonlinear sigma-model, two-dimensional self-dual Yang-Mills equations and some modification of the vector Calapso equation.
