Sato that all Schur function s are solutions of the KP hierarchy and that a general solution can be exp ressed  as a possibly infinite linear combination of these Schur functions . However\, not all linear combinations are solutions of this KP hierarchy . In this talk I will address the topic of polynomial solutions of various hierarchies. In particular\, I will give a simple formula that describes all polynomial solutions for both the KP and Gelfand-Dickey hierarchies.  This is based on joint work with Victor Kac.\n\nWEB - Please fill in this form: https://forms.gle/S1NcNQ8BxkzfAXcj9\n DTSTART:20210316T193000Z DTEND:20210316T203000Z SUMMARY:Prof. Johan van de Leur (Utrecht University) URL:/mathstat/channels/event/prof-johan-van-de-leur-ut recht-university-329587 END:VEVENT END:VCALENDAR
