报告摘要
I will talk about two closely related blow-up results. The first is a non-asymptotically self-similar blow-up for the De Gregorio equation, using a novel mecanism that models the blow-up on a Riccati-type infinite system of ODEs. The second is a non-asymptotically self-similar blow-up for the 3D incompressible Euler equation without swirl, which improves on Elgindi's construction, in the sense that the number of singularities in the initial data is minimized.
