报告内容:Recently, Hone, Novikov and Wang have given a list of so-called generalized short pulse equations which are integrable. Among them, three are related to the 3-reductions of BKP/CKP hierarchies. One is named reduced Ostrovsky equation and its derivative form can be viewed as the short wave model of the Degasperis-Procesi (DP) equation, the second one can be viewed as the short wave model of the Novikov equation and the third one is connected to the first two via Miura transformation.

In the first part of my talk, I will make all above facts clear. Then I will construct their integrable semi-discretizations based on their connections of 3-reduction of negative BKP/CKP hierarchies.
