Elementary Continued Fractions for Linear Combinations of Zeta and L Values

Henri Cohen

We show how to obtain infinitely many continued fractions for certain Z-linear combinations of zeta and L values. The methods are completely elementary.

Factorizations of Eisenstein Series of Level up to 4

Henri Cohen

We show that the most standard Eisenstein series such as or , and also the function , are in a natural way the product of two conjugate Eisenstein…

Rational Hypergeometric Ramanujan Identities for : Survey and Generalizations

Henri Cohen, Jesús Guillera

We give a simple unified proof for all existing rational hypergeometric Ramanujan identities for , and give a complete survey (without proof) of several generalizations: ratio…

Computing L-Functions of Quadratic Characters at Negative Integers

Henri Cohen

We survey a number of different methods for computing for a Dirichlet character , with particular emphasis on quadratic characters. The main conclusion is that when $…

Lambert -Function Branch Identities

Henri Cohen

After defining in detail the Lambert -function branches, we give a large number of exact identities involving (infinite) symmetric functions of these branches, as well as geomet…

Modular Forms in Pari/GP

Karim Belabas, Henri Cohen

We give theoretical and practical information on the Pari/GP modular forms package available since the spring of 2018. Thanks to the use of products of two Eisenstein series, this…
