Comment on Understanding the most beautiful equation in MathematicsComments−j2kun13yThere's some even more important gaps regarding analytic continuations of functions to complex numbers (and the resulting power series expansions). You can prove it this way, but it's not at all rigorous by today's standards.−aditgupta13yThis was more for basic understanding. There can be a follow-up article with a more rigorous approach :) The same was done here - http://functionspace.org/articles/17/Solving----sum----1----...
