In number theory, the Dirichlet hyperbola method is a technique to evaluate the sum where are multiplicative functions with , where is the Dirichlet convolution. It uses the fact that (Wikipedia).

(ML 7.8) Dirichlet-Categorical model (part 2)
The Dirichlet distribution is a conjugate prior for the Categorical distribution (i.e. a PMF a finite set). We derive the posterior distribution and the (posterior) predictive distribution under this model.

Dirichlet Eta Function - Integral Representation
Today, we use an integral to derive one of the integral representations for the Dirichlet eta function. This representation is very similar to the Riemann zeta function, which explains why their respective infinite series definition is quite similar (with the eta function being an alte rna

[ANT07] Units and logarithm space (+ bonus theorems)
There are infinitely many units in Z[â2]. How can we write them down? How can we figure out their multiplicative structure? (Plus, now that we've come this far, a few theorems to make the link between this course and more traditional courses.)

James Maynard: Half-isolated zeros and zero-density estimates
We introduce a new zero-detecting method which is sensitive to the vertical distribution of zeros of the zeta function. This allows us to show that there are few 'half-isolated' zeros, and allows us to improve the classical zero density result to N(Ï,T)âŠT24(1âÏ)/11+o(1) if we assume that t
