Abstract:
The zetafunction is one of the most important nonelementary functions in mathematics. It was studied by many great mathematicians and it continues to receive considerable attention from the modern researchers. One of its most important properties is its functional equation, which is traditionally attributed to Bernhard Riemann. The seminar is devoted to the history of this formula and to that of some similar Lfunctions, as well as to the contributions of various mathematicians in its discovery and proof (Euler, Malmsten, Schlömilch, Kinkelin, Riemann). We will focus our attention more in details on the contributions of Leonhard Euler and on those of a littleknown Swedish mathematician Karl Malmsten, who was the first to rigorously prove such a kind of relationships and to obtain a number of other important results (e.g. the Fourier series for the logarithm of the gammafunction), which were later attributed to other mathematicians.
