Integrable discretizations for a generalized sine-Gordon equation and the reductions to the sine-Gordon equation and the short pulse equation

Han-Han Sheng, Bao-Feng Feng, Guo-Fu Yu

In this paper, we propose fully discrete analogues of a generalized sine-Gordon (gsG) equation $u_{t x} = (1 + ν \partial_{x}^{2}) sin u$ . The bilinear equations of the discrete…

Multiple skew orthogonal polynomials and 2-component Pfaff lattice hierarchy

Shi-Hao Li, Bo-Jian Shen, Jie Xiang +1

In this paper, we introduce multiple skew-orthogonal polynomials and investigate their connections with classical integrable systems. By using Pfaffian techniques, we show that mul…
