Automorphic inflation [PDF]

open access: yesPhysics Letters B, 2015
A framework of inflation is formulated based on symmetry groups and their associated automorphic functions. In this setting the inflaton multiplet takes values in a curved target space constructed from a continuous group G and a discrete subgroup Γ.

Extremal p-Adic L-Functions

open access: yesMathematics, 2021
In this note, we propose a new construction of cyclotomic p-adic L-functions that are attached to classical modular cuspidal eigenforms. This allows for us to cover most known cases to date and provides a method which is amenable to generalizations to ...

Two string theory flavours of generalised Eisenstein series

open access: yesJournal of High Energy Physics, 2023
Generalised Eisenstein series are non-holomorphic modular invariant functions of a complex variable, τ, subject to a particular inhomogeneous Laplace eigenvalue equation on the hyperbolic upper-half τ-plane.

Greens functions, Hamiltonians and modular automorphisms [PDF]

open access: yesCommunications in Mathematical Physics, 1976
We demonstrate, under circumstances that allow the construction of a “thermodynamic” hamiltonian, that Gibbs equilibrium states ω are modular states in the Tomita-Takesaki sense. The thermodynamic Greens functionsG are connected to these modular states, and the associated group of modular automorphisms σ, by the identification $$G(A, B; t) = \omega (

The Group of Automorphisms of the Modular Function Field

open access: yesInventiones Mathematicae, 1971
Let F be the field of modular functions of all levels on the upper half plane, with, say, Fourier coefficients in the field of all roots of unity. One can define in an obvious way two types of automorphisms of F. First we note that F is a Galois extension of Q(j), where j is the modular function. We have therefore the Galois group U of automorphisms of

Squares of Automorphic Forms on Quaternion Algebras and Central Values ofL-Functions of Modular Forms

open access: yesJournal of Number Theory, 1999
Let \(f\) be a newform of weight \(k\) and trivial character with respect to \(\Gamma_0(N)\) for squarefree \(N\) and assume \(f\) has eigenvalue \(-1\) under the Fricke involution \(w_N\). In this paper, the authors characterize the vanishing of the central value \(L(f,k/2)\) of the \(L\)-function of \(f\) completely in terms of elementary properties ...

The automorphism group of Leech lattice and elliptic modular functions

open access: yesJournal of the Mathematical Society of Japan, 1985
Certain finite groups G with a representation \(\rho\) of degree d \(| 24\) over \({\mathbb{Q}}\) are shown to have moonshine properties in the sense of \textit{J. H. Conway} and \textit{S. P. Norton} [Bull. Lond. Math. Soc. 11, 308-339 (1979; Zbl 0424.20010)].
