Abstract:
\r\nAs anticipated by Onsager's conjecture, low-regularity solutions of the Euler equations exhibit greater flexibility than classical solutions. In the first part of this talk we focus on steady solutions, showing that in the low-regularity regime their streamlines can realize any prescribed topology, a phenomenon that cannot occur for classical solutions. The key tool is a novel implementation of convex integration that preserves the topology of the streamlines throughout the iteration. In the second part we extend these ideas to the MHD equations, constructing continuous weak solutions with constant nonzero helicity that nevertheless fail to conserve energy and cross helicity.
