Speaker: Ricardo Grande Izquierdo Abstract: In this talk, we will propose a linear SPDE that serves as a toy model for thetransfer of energy in fully developed fluid turbulence. In order to dissipate the energythat is constantly injected into the system,… Read moreLinear model of turbulent cascades and fractional fields

Speaker: Basile Gallet Abstract: Decades of investigation of the Rayleigh-Bénard (RB) thermal convection setup indicate that the heat transport is strongly restricted by boundary layers near the hot and cold solid plates. This prevents the unambiguous observation of the ‘ultimate’… Read moreRadiatively driven convection: towards the ultimate scaling regime and beyond

Speaker: Michal Shavit Abstract: Strongly dispersive waves in geophysical fluid dynamics occur on scales fromcentimetres to thousands of kilometres and contribute in an essential way to the long-term nonlinear dynamics of the climate system.  Examples include internal inertia–gravitywaves and Rossby waves,… Read moreThe role of sign indefinite invariants in shaping turbulent cascades.

Speaker: Nikolay Tzvetkov Abstract: We will discuss the nonlinear Schrödinger equation with data distributedaccording to gaussian fields. These fields are invariant under the free evolution and thequestion is how much the nonlinear interaction affects the invariance property. We willpresent a… Read moreEvolution of gaussian fields by the flow of the nonlinear Schrödinger equation
