The neutrix composition  of a distribution  and a locally summable function  is said to exist and be equal to the distribution  if the neutrix limit of the sequence  is equal to  where  and  is a certain sequence of infinitely differentiable functions converging to the Dirac delta-function  It is proved that if  denotes the distribution  then the neutrix composition  exists and
