Of course, the series 1+2+3+4+... diverges. However, it is sometimes possible to assign finite values to such divergent series. This series can be assigned a finite value by means of zeta function regularisation. In this seminar, I will introduce the Riemann zeta function and show how the definition of this function for certain real values can be extended to the complex plane. Along the way I will show how 1+2+3+4+… can be assigned the value -1/12. To conclude, I will talk about the Riemann hypothesis.
