In mathematics, singular integrals are central to abstract harmonic analysis and are intimately connected with the study of partial differential equations. Broadly speaking a singular integral is an integral operator

$T(f)(x)=\int K(x,y)f(y)dy,$

whose kernel function K : Rⁿ×Rⁿ → Rⁿ is singular along the diagonal x=y.
