Workshop on Recent developments in incompressible fluid dynamics

From the Monge transportation problem to Einstein's gravitation through Euler's Hydrodynamics
Yann Brenier
10:30am|Simonyi 101 and Remote Access

Abstract: The quadratic Monge optimal transportation problem can be revisited in Euler's language of Hydrodynamics as was explained by Jean-David Benamou and the speaker about 20 years ago. It turns out that Einstein's theory of gravitation, at...

A detailed characterization of the hypersurface of pre-shocks for the Euler equations
Steve Shkoller
2:00pm|Simonyi 101 and Remote Access

Abstract. I will describe a new geometric approach for the shock formation problem for the Euler equations.   A complete description of the solution along the hypersurface of first singularities or preshocks will be given.

Local Dissipation of Energy for Continuous Incompressible Euler Flows
Philip Isett
4:00pm|Simonyi 101 and Remote Access

Abstract:   I will discuss the construction of continuous solutions to the incompressible Euler equations that exhibit local dissipation of energy and the surrounding motivations.  A significant open question, which represents a strong form of the...

Small scale formations in the incompressible porous media equation
Yao Yao
9:00am|Simonyi 101 and Remote Access

Abstract: The incompressible porous media (IPM) equation describes the evolution of density transported by an incompressible velocity field given by Darcy’s law. Here the velocity field is related to the density via a singular integral operator...

Properties of mixing BV vector fields
Stefano Bianchini
10:30am|Simonyi 101 and Remote Access

Abstract: We consider the density properties of divergence-free vector fields $b \in L^1([0,1],\BV([0,1]^2))$ which are ergodic/weakly mixing/strongly mixing: this means that their Regular Lagrangian Flow $X_t$ is an ergodic/weakly mixing/strongly...

D'Alembert Principle and weak solutions of the Euler equations
Alexander Shnirelman
4:00pm|Simonyi 101 and Remote Access

Abstract: Let M be a smooth manifold in an Euclidean space; consider the motion of a material point on M in absence of friction. The D'Alembert Principle says that the acceleration vector is orthogonal to the tangent space to M, and this fact...
