An integrable semi-discrete Degasperis–Procesi equation
An integrable semi-discrete Degasperis–Procesi equation
Based on our previous work on the Degasperis–Procesi equation (Feng et al J. Phys. A: Math. Theor. 46 045205) and the integrable semi-discrete analogue of its short wave limit (Feng et al J. Phys. A: Math. Theor. 48 135203), we derive an integrable semi-discrete Degasperis–Procesi equation by Hirota's bilinear method. …
