The gamma function gives product of f(x)=x; in document FractionalOperator.pdf (downloadable from site http://researchpages.my-host.org/home/) I've published a document about product of function

f(x)=sin(piGreek*k/x)

where k is a real constant and x is in the set of real numbers; moreover I've defined a function that is discontinuous only on prime numbers.
Please let me know what do you think about this results.
Thanks
