Özet

Let F be a distribution in D' and let f be a locally summable function. The composition F(f(x)) of F and f is said to exist and be equal to the distribution h(x) if the limit of the sequence {F-n(f(x))}. is equal to h(r), where F-n(x) = F(x) * delta(n)(x) for n = 1, 2, .... and {delta(n)(x)} is a certain regular sequenceconverging to the Dirac delta function. It is proved that the neutrix composition delta(s)[cosh(-1) (x(+)(1/r) +1)] exists and
