WebIn mathematics, an integral ∫ (U+222B) is the continuous analog of a sum, which is used to calculate areas, volumes, and their generalizations.Integration, the process of computing an integral, is one of the two fundamental operations of calculus, the other being differentiation.Integration started as a method to solve problems in mathematics and … 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
