V. E. Adler, A. P. Veselov

摘要:

研究了四元图上可积离散方程的初值问题。本文给出了问题适定性的几何判据,讨论了离散势KdV和线性波动方程的解与规则正方形晶格中的局域缺陷相互作用的影响。扭结和孤子的各种四图,包括准周期平铺的例子。

英文摘要:

Initial value problems for the integrable discrete equations on quad-graphs are investigated. A geometric criterion of the well-posedness of such a problem is found. The effects of the interaction of the solutions with the localized defects in the regular square lattice are discussed for the discrete potential KdV and linear wave equations. The examples of kinks and solitons on various quad-graphs, including quasiperiodic tilings, are presented.
