 ">Emergent hydrodynamics of soliton gases in nonlinear dispersive waves</a
 >\nby Gennady El (Northumbria University) as part of Nonlinear Waves and C
 oherent Structures Webinar Series\n\n\nAbstract\nSoliton gases represent l
 arge random ensembles of interacting solitons that display non-trivial eme
 rgent\, macroscopic\, behaviours ultimately determined by the properties o
 f the elementary two-soliton collisions. Originally introduced by V. Zakha
 rov in 1971 the concept of soliton gas has recently attracted significant 
 interest from both mathematics and physics communities. The large-scale ev
 olution of non-equilibrium dense soliton gases in integrable dispersive sy
 stems is described by a nonlinear integro-differential kinetic equation fo
 r the density of states in the spectral (Lax) phase space. In my talk\, I 
 will outline the main ideas of the spectral theory of soliton gases and it
 s applications to a range of fundamental dispersive hydrodynamic phenomena
 : from modulational instability to dispersive shock waves.\n
