The Mathematical center in Akademgorodok invites you to take part in the on
October 21 at 4 pm Novosibirsk time (UTC+7).
The seminar's heads: A. E. Mironov, I. A. Taimanov, Huijun Fan, Youjin Zhang.
During the seminar
Maxim Pavlov (Lebedev Physical Institute RAS) will present his talk
"Non-diagonalisable Hydrodynamic Type Systems, Integrable by Tsarev's Generalised Hodograph Method".
We present a wide class of non-diagonalisable hydrodynamic type systems, which can be integrated by Tsarev' s generalised hodograph method. This class of hydrodynamic type systems contains Jordan blocks 2x2 only. The Haantjes tensor has vanished. This means such 2N component hydrodynamic type systems possess N Riemann invariants and N double eigenvalues only.
First multi-component example was extracted from El's nonlocal kinetic equation, describing dense soliton gas. All conservation laws and commuting flows were found. A general solution is constructed.
