I read that for the divergent series:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

1+2+3+...=-\frac{1}{12}

[/tex]

It was said that is obtained by using the so called regularization technique (zeta function regularization?). I would like to see an explicit proof for that. Can anybody suggest a suitable source where this can be found?
