Two General Series Identities Involving Modified Bessel Functions and a Class of Arithmetical Functions

Bruce C. Berndt, Atul Dixit, Rajat Gupta +1

We consider two sequences and , , generated by Dirichlet series $$\sum_{n=1}^{\infty}\frac{a(n)}{λ_n^{s}}\qquad\text{and}\qquad \sum_{n=1}^{\infty}\fra…

Extended Higher Herglotz function \textup{II}

Rajat Gupta, Rahul Kumar

Very recently, Radchenko and Zagier revived the theory of Herglotz functions. The main goal of the article is to show that one of the formulas on page 220 of Ramanujan's Lost Noteb…

A Class of Identities Associated with Dirichlet Series Satisfying Hecke's Functional Equation

Bruce C. Berndt, Atul Dixit, Rajat Gupta +1

We consider two sequences and , , generated by Dirichlet series of the forms $$\sum_{n=1}^{\infty}\frac{a(n)}{λ_n^{s}}\qquad\text{and}\qquad \sum_{n=1}…

Extended higher Herglotz functions I. Functional equations

Atul Dixit, Rajat Gupta, Rahul Kumar

In 1975, Don Zagier obtained a new version of the Kronecker limit formula for a real quadratic field which involved an interesting function which is now known as the \emph{H…
