Encoding Fourier multipliers in matrix algebras Fourier multipliers are among the most important operators in analysis. They act on a given function $f$ by pointwise multiplication of its Fourier transform with a fixed function $f (m f pt )^$. This action can be vastly extended using more general notions of Fourier transform via group representation theory. In this talk, we […]
