Terrà un seminario dal titolo:



*“Bilinear multipliers from the perspective of a joint functional calculus”*



*Abstract:*

*Even though the Laplacian does not satisfy the Leibniz rule, it** does
satisfy a fractional Leibniz rule in terms of Lp estimates. This can be
proved by using the Coifman-Meyer theory of bilinear Fourier multipliers.
Noting that the bilinear multipliers may be defined in terms of a joint
functional calculus for partial derivatives, we propose a spectral
generalization of the theory outside of the Fourier transform framework. We
focus on Coifman-Meyer type multiplier theorems and their relations with
fractional Leibniz rules. Examples admitted by our theory include bilinear
multipliers for: the discrete Laplacian, the general Dunkl Laplacian, and
the Jacobi operator. The talk is mostly based on work in progress.*



Tutti gli interessati sono invitati a partecipare.
