In mathematics, a Hilbert–Schmidt integral operator is a type of integral transform. Specifically, given a domain (an open and connected set) Ω in n-dimensional Euclidean space R , a Hilbert–Schmidt kernel is a function k : Ω × Ω → C with (that is, the L (Ω×Ω; C) norm of k is finite), and the associated Hilbert–Schmidt integral operator is the operator K : L (Ω; C) → L (Ω; C) given by florist in keysborough victoriaWeb1 de set. de 1998 · Abstract.
