Sonata 17 grant 2021/43/D/ST1/00667.
Financed by the National Science Centre, Poland.
03-10-2022 to 02-10-2025.
970,740 PLN.

Project goal:

The project concerns the construction and use of new function spaces to study local smoothing for wave equations. This builds upon work which connects local smoothing estimates for the Euclidean wave equation, as well as the lp decoupling inequality for the light cone, to the Hardy spaces for Fourier integral operators.
For a more accessible (albeit imprecise) description, see here (i po polsku).
