Congruences with Eisenstein series and -invariants [PDF]

open access: yesCompositio Mathematica, 2019
We study the variation of$\unicode[STIX]{x1D707}$-invariants in Hida families with residually reducible Galois representations. We prove a lower bound for these invariants which is often expressible in terms of the$p$-adic zeta function. This lower bound forces these$\unicode[STIX]{x1D707}$-invariants to be unbounded along the family, and we conjecture

Relation between Borweins’ Cubic Theta Functions and Ramanujan’s Eisenstein Series

open access: yesJournal of Applied Mathematics, 2021
Two-dimensional theta functions were found by the Borwein brothers to work on Gauss and Legendre’s arithmetic-geometric mean iteration. In this paper, some new Eisenstein series identities are obtained by using (p, k)-parametrization in terms of Borweins’

Algorithms and tools for iterated Eisenstein integrals

open access: yesJournal of High Energy Physics, 2020
We present algorithms to work with iterated Eisenstein integrals that have recently appeared in the computation of multi-loop Feynman integrals. These algorithms allow one to analytically continue these integrals to all regions of the parameter space ...

A p-adic Eisenstein measure for vector-weight automorphic forms [PDF]

open access: yes, 2014
We construct a p-adic Eisenstein measure with values in the space of vector-weight p-adic automorphic forms on certain unitary groups. This measure allows us to p-adically interpolate special values of certain vector-weight C-infinity automorphic forms ...

Eisenstein series for infinite-dimensional U-duality groups [PDF]

open access: yes, 2012
We consider Eisenstein series appearing as coefficients of curvature corrections in the low-energy expansion of type II string theory four-graviton scattering amplitudes.

Effective Lower Bounds for L(1,{\chi}) via Eisenstein Series [PDF]

open access: yes, 2016
We give effective lower bounds for $L(1,\chi)$ via Eisenstein series on $\Gamma_0(q) \backslash \mathbb{H}$. The proof uses the Maass-Selberg relation for truncated Eisenstein series and sieve theory in the form of the Brun-Titchmarsh inequality.

Eisenstein series and convolution sums [PDF]

open access: yesThe Ramanujan Journal, 2018
We compute Fourier series expansions of weight $2$ and weight $4$ Eisenstein series at various cusps. Then we use results of these computations to give formulas for the convolution sums $ \sum_{a+p b=n} (a) (b)$, $ \sum_{p_1a+p_2 b=n} (a) (b)$ and $ \sum_{a+p_1 p_2 b=n} (a) (b)$ where $p, p_1, p_2$ are primes.

One-loop open-string integrals from differential equations: all-order α′-expansions at n points

open access: yesJournal of High Energy Physics, 2020
We study generating functions of moduli-space integrals at genus one that are expected to form a basis for massless n-point one-loop amplitudes of open superstrings and open bosonic strings.

Quantum Variance for Eisenstein Series [PDF]

open access: yesInternational Mathematics Research Notices, 2019
Abstract In this paper, we prove an asymptotic formula for the quantum variance for Eisenstein series on $\operatorname{PSL}_2(\mathbb{Z})\backslash \mathbb{H}$. The resulting quadratic form is compared with the classical variance and the quantum variance for cusp forms.
