摘要:

Discrete BKP hierarchy and its pfaffian solution were constructed by Miwa, Hirota and Tsujimoto. It is known that the discrete BKP and continuous BKP hierarchies are connected via Miwa transformation. In this talk, we will show a BKP bilinear equation with both positive and negative flows can be constructed from the discrete BKP equation as well via Miwa transformation. Moreover, a shallow water wave equation and the reduced Ostrovsky equation can be derived by reductions. Based on this finding, we are able to construct semi-discrete BKP equation and further semi-discrete reduced Ostrovsky equation. Some open problems will also be discussed.
