Abstract:
In this talk, we consider a Euler-Riesz system and establish a higher integrability estimate for the density. This is achieved through a reformulation of the system and compensated integrability. We will also discuss connections to harmonic analysis, particularly the introduction of a bilinear fractional integral operator, whose uniform estimates are derived via restricted weak-type endpoint bounds and Marcinkiewicz interpolation.
