Norm of convolution operator

Web10 de out. de 2024 · In this note we present some results concerning the convergence of iterates of convolution operators in group algebras. Recall that an infinite matrix \(A=[a_{n,k}]_{n,k=0}^{\infty}\) is said to be regular if it transforms each convergent sequence, viewed as a column vector, into another convergent one with the same limit. WebExample. differentiation, convolution, Fourier transform, Radon transform, among others. Example. If A is a n × m matrix, an example of a linear operator, then we know that ky −Axk2 is minimized when x = [A0A]−1A0y. We want to solve such problems for linear operators between more general spaces. To do so, we need to generalize “transpose”
