In a recent lecture on String Theory, we encountered the divergent sum 1+2+3+.... when calculating the zero mode Virasoro operator in bosonic String Theory. This divergent sum is then set equal to a finite negative constant - the argument for doing so was a comparison with the definition of the Zeta function. However, is still have trouble with this argument, and my question is, wether there are any further justifications for taking this step. Thank you for your answers!(adsbygoogle = window.adsbygoogle || []).push({});
