报告摘要：

Based on a two-component reduced Ostrovsky equation, or a short wave model of the two-component Degasperis-Proceli equation we recently proposed, we will show how to construct its integrable semi-discretization of this new model. We start with a modied BKP hierarchy, which is a Backlund transformation of the extended BKP hierarchy which gives the two-component reduced Ostrovsky equation, an integrable semi-discrete analogue of the two-component reduced Ostrovsky equation is constructed by dening an appropriate discrete hodograph transformation and dependent variable transformations. Meanwhile, its N-soliton solution in terms of pfaffian is also provided. Interestingly, the backward difference form of above semi-discrete two-component reduced Ostrovsky equation gives rise to the integrable semi-discretization of the short wave model of a two-component DP equation, which strongly implies the integrability of the two-component DP equation.
