One of the best things I saw this week: a paper uncovering alien signals in the Riemann Zeta function. April Fools always brings peak creativity.

Next term I'll be teaching a course on #Riemann surfaces for first year graduate, last year undergraduate students. Suggestions on books and syllabi?

Recently there has been some progress - a proof creates stricter limits on potential exceptions to the famous #Riemann hypothesis

It does diverge. It has no sum.
However, the uniquely valued #Riemann #ZetaFunction can be analytically continued into the left half-plane where we find zeta(-1)=-1/12 (which 'looks like' 1+2+...). #Cesàro #summation will get you part of the way there also, and, as you say, yields the same result; presumably due to some ultimate cosmic logical rightness :-)
I very strongly recommend BP's superb exposition of this issue

`Two years later, in 1849, he returned to Göttingen to pursue his PhD with Gauss, completing his thesis in 1851 on the theory of complex variables, the basis for what we now call Riemann surfaces. Gauss described Riemann as having “a gloriously fertile originality” in his report on the thesis, and two years later, when #Riemann was required to give a lecture to land a faculty position at Göttingen, Gauss assigned his star pupil the topic of the foundations of #geometry`

DOMINATED CONVERGENCE THEOREM
Lebesgue's dominated convergence theorem provides sufficient conditions under which pointwise convergence of a sequence of functions implies convergence of the integrals. It's one of the reasons that makes #Lebesgue integration more powerful than #Riemann integration. The theorem an be stated as follows:

Riemann zeta function
Have you ever heard that the sum of all natural numbers is Of course not; this doesn't make sense in the usual sum, but using a summation method based on analytic continuation of the Riemann zeta function leads to the following result.
The Riemann zeta function is defined as:
for
It can be extended to a meromorphic function with only a simple pole at

The unproved Riemann hypothesis states that the nontrivial zeros of the Riemann zeta function occur only on the critical line
With an implementation of the zeta function in #JavaScript one has a proof near the origin via #visualization. The real part of the function is blue, imaginary red:

Manipulating the imaginary part of the argument along the critical strip shows immediately that zeros only occur on the critical line for an imaginary part of approximately

Il paraît que ça bouge autour de la #conjecture de #Riemann ! .. #mathematiques #maths
There is this really awesome series on YouTube about the Riemann-Zeta function which is currently running and seems to want to explain all the mathematic objects related to it properly it would be awesome if you could show the video series some love while it's running. https://youtu.be/4bzSFNCiKrk
