Cusp forms and parabolic cohomology classes for symmetric spaces of rank one

Roelof Bruggeman, YoungJu Choie, Roberto Miatello +1

For any rank-one Riemannian symmetric space S of non-compact type and any discrete, cofinite, non-cocompact, torsion-free group of orientation-preserving Riemannian isometries…

Kronecker second limit formula for real quadratic fields

YoungJu Choie, Rahul Kumar

In this paper, the second Kronecker ``limit" formula for a real quadratic field is established for the first time. More precisely, we obtain the second Kronecker limit formula of Z…

Period Function of Maass forms from Ramanujan's Lost Notebook

YoungJu Choie, Rahul Kumar

The Lost Notebook of Ramanujan contains a number of beautiful formulas, one of which can be found on its page 220. It involves an interesting function, which we denote as $\mathcal…

On Rankin-Cohen Brackets of Hecke Eigenforms and Modular Forms of Half-Integral Weight

YoungJu Choie, Winfried Kohnen, Yichao Zhang

We generalize the linear relation formula between the square of normalized Hecke eigenforms of weight and normalized Hecke eigenforms of weight , to Rankin-Cohen brackets o…

Twisted Kronecker series and periods of modular forms on

Clifford Blakestad, YoungJu Choie

We introduce an infinite family of Kronecker series twisted by characters. As an application, we give a closed formula for the sum of all Hecke eigenforms on multiplied b…
