报告摘要:
In this talk, we first give determinant solution to the modified modified Camassa-Holm (mCH) equation based on the Hirota's bilinear method. An integrable semi-discrete analogue of the mCH equation is constructed. The keys of the construction are bilinear forms, determinant structure of solutions and periodic 2-reduction of tau-function. N-soliton solutions of the continuous and semi-discrete modified Camassa–Holm equations are expressed in the form of Casorati determinants. In the continuous limit, we show that the semi-discrete mCH equation converges to the continuous version. This is a joint work with Bao-Feng Feng and Han-Han Sheng.
