An Integral Representation of Standard Automorphic L Functions for Unitary Groups
Let F be a number field, G a quasi-split unitary group of rank n. We show that given an irreducible cuspidal automorphic representation π of G(A), its (partial) L function LS(s,π,σ) can be represented by a Rankin-Selberg-type integral involving cusp ...

Integral forms of Kac-Moody groups and Eisenstein series in low dimensional supergravity theories [PDF]
Kac-Moody groups $G$ over $\mathbb{R}$ have been conjectured to occur as symmetry groups of supergravities in dimensions less than 3, and their integer forms $G(\mathbb{Z})$ are conjecturally U-duality groups. Mathematical descriptions of $G(\mathbb{Z})$,

Basis decompositions of genus-one string integrals
One-loop scattering amplitudes in string theories involve configuration-space integrals over genus-one surfaces with coefficients of Kronecker-Eisenstein series in the integrand.

Generating series of all modular graph forms from iterated Eisenstein integrals
We study generating series of torus integrals that contain all so-called modular graph forms relevant for massless one-loop closed-string amplitudes. By analysing the differential equation of the generating series we construct a solution for their low ...

Kac--Moody groups and automorphic forms in low dimensional supergravity theories
Kac--Moody groups $G$ over $\mathbb{R}$ have been conjectured to occur as symmetry groups of supergravity theories dimensionally reduced to dimensions less than 3, and their integral forms $G(\mathbb{Z})$ conjecturally encode quantized symmetries.

Faber's socle intersection numbers via Gromov–Witten theory of elliptic curve
Abstract The goal of this very short note is to give a new proof of Faber's formula for the socle intersection numbers in the tautological ring of Mg$\mathcal {M}_g$. This new proof exhibits a new beautiful tautological relation that stems from the recent work of Oberdieck–Pixton on the Gromov–Witten theory of the elliptic curve via a refinement of ...

Modular invariance in finite temperature Casimir effect
The temperature inversion symmetry of the partition function of the electromagnetic field in the set-up of the Casimir effect is extended to full modular transformations by turning on a purely imaginary chemical potential for adapted spin angular ...

The Eisenstein elements of modular symbols for level product of two distinct odd primes
We explicitly write down the Eisenstein elements inside the space of modular symbols for Eisenstein series with integer coefficients for the congruence subgroups {\Gamma}_0 (pq) with p and q distinct odd primes, giving an answer to a question of Merel in

Note on Siegel-Eisenstein series [PDF]
Let \(\Gamma_n(K)\) stand for the Siegel modular group if \(K=\mathbb{Q}\) resp. for the Hermitian modular group of degree \(n\) over \(K\) if \(K\) is an imaginary quadratic number field of class number 1. Denote by \(E^{(n)}_{k,K} (Z,s)\) the attached Siegel-Eisenstein series of weight \(k\) with factor of convergence \((\text{det Im} M \langle Z ...
