We shall discuss the concept of sparse dominations of singular integral operators, in particular for those operators whose kernel do not satisfy any regularity estimate. Such sparse dominations lead to sharp weighted norm estimates and weighted weak-type estimates for operators such as Riesz transforms and multipliers associated with a second order elliptic operator.
