Theory of surfaces,In 1828 Gauss published his investigations on surfaces (. 6 (1828)). This great work, which as late as 1900 was regarded by Darboux as the most self-contained and useful introduction to the study of differential geometry, was Gauss’s most important published contribution to geometry.

Harmonic analysis,In the middle of the 18. century the most important mathematicians were concerned with the solution of the equation of the vibrating string (in the xy-plane) .fixed at the points (0,0) and (0,.). Here t denotes time and c is a parameter depending on the unit of mass.

Prime numbers in arithmetic progressions,Already in the ., Euclid found the theorem that there are infinitely many prime numbers. Suppose that there are only finitely many and that these are the numbers p. ,…,p. . Then we consider the number p.p.…p.+1. It contains none of the numbers p. ,…,p. as a prime factor. Therefore, there must be still more primes.

The beginnings of complex function theory,The beginning of the 19. century marked the transition from the study of real functions to the study of complex functions.

Riemann surfaces,One of the main questions of function theory, already in the 18. century and above all in the 19., was the study of integrals of algebraic functions. By an . we initially mean an antiderivative, i.e. a function whose derivative equals the given function.

Meromorphic differentials and functions on closed Riemann surfaces,The main goal of this chapter is to present the basic properties of meromorphic functions on closed Riemann surfaces. To do this we must first carry over the principles of Cauchy’s function theory from the plane to Riemann surfaces.
