Let be the expression:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \Product_{p}(1+x^{p}) [/tex] where the product is extended to over all primes.

of course is some kind of generalizating the function [tex] \Product_{m=1}^{\infty}(1+x^{m}) [/tex] wich is some partition function..but what happens when is evaluated only in primes?..thanks.
