Norm of convolution operator
Web1 de dez. de 2024 · In this paper we prove that the ball is a maximizer of the Schatten p-norm of some convolution type integral operators with non-increasing kernels among all domains of a given measure in R d.We also show that the equilateral triangle has the largest Schatten p-norm among all triangles of a given area.Some physical motivations for our … Webwhere H ∗ is the dual space of H.The norm induced by this inner product is the Hilbert–Schmidt norm under which the space of Hilbert–Schmidt operators is complete (thus making it into a Hilbert space). The space of all bounded linear operators of finite rank (i.e. that have a finite-dimensional range) is a dense subset of the space of …
