A nonlinear and probabilistic approach to the periodic Carleson convergence problem
Daniel Eceizabarrena - BCAM
Given the solution $u = u(x,t)$ to the Schrodinger equation with initial data $f$, when can we say that $\lim_{t \to 0} u(x,t) = f(x)$ pointwise in $x$? More precisely, what Sobolev regularity do we require for $f$ for this property to hold? This is known as Carleson's convergence problem.
I will discuss recent results in the periodic setting, both for the linear and non-linear Schrödinger equations, and how a probabilistic approach can dramatically decrease the Sobolev regularity required for the initial data.
This talk is in the context of the recent work https://arxiv.org/abs/2608.17100 in collaboration with Pablo Merino (BCAM).
