Combinatorics of traces of Hecke operators [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
We investigate the combinatorial properties of the traces of the n th Hecke operators on the spaces of weight 2k cusp forms of level N . We establish examples in which these traces are expressed in terms of classical objects in enumerative combinatorics (e.g., tilings ...

Statistics of Hecke eigenvalues for GL(𝑛)

open access: yesForum mathematicum, 2018
A two-dimensional central limit theorem for the eigenvalues of GL ⁢ ( n ) {\mathrm{GL}(n)} Hecke–Maass cusp forms is newly derived. The covariance matrix is diagonal and hence verifies the statistical independence between the real and imaginary parts of ...

Hypergeometric motives from Euler integral representations

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We revisit certain one‐parameter families of affine covers arising naturally from Euler's integral representation of hypergeometric functions. We introduce a partial compactification of this family. We show that the zeta function of the fibers in the family can be written as an explicit product of L$L$‐series attached to nondegenerate ...

A bar operator for involutions in a Coxeter group [PDF]

open access: yes, 2012
In [LV] the authors defined a Hecke algebra action and a bar involution on a vector space spanned by the involutions in a Weyl group. In this paper we give a new definition of the Hecke algebra action and the bar operator which, unlike the one in [LV ...

Orthogonality and Hecke operators

open access: yesProceedings - Mathematical Sciences, 2009
In this article we analyze orthogonality relations between old forms and the connection to the theory of Hecke operators.

Exploring consumption profiles, consumer experience and quality claims of Canary Islands' cider (Spain): A multidimensional analysis

open access: yesAgribusiness, Volume 42, Issue 1, Page 381-399, Winter 2026.
Abstract The exponential expansion of the global cider market positions it as a viable alternative to traditional choices such as wine and beer. Nevertheless, there exists a paucity of research examining the various factors influencing consumer interest in cider.

Hecke Operators and Hilbert Modular Forms [PDF]

open access: yes, 2008
Let F be a real quadratic field with ring of integers O and with class number 1. Let Gamma be a congruence subgroup of GL_2 (O). We describe a technique to compute the action of the Hecke operators on the cohomology H^3 (Gamma; C). For F real quadratic this cohomology group contains the cuspidal cohomology corresponding to cuspidal Hilbert modular ...

Weyl’s law for Hecke operators on GL(n) over imaginary quadratic number fields [PDF]

open access: yes, 2013
We prove Weyl's law for Hecke operators acting on cusp forms of ${\rm GL}(n)$ over imaginary quadratic number fields together with an upper bound for the error term depending explicitly on the Hecke operator.

Thermal noise lowers the accuracy of rotationally invariant harmonics of diffusion MRI data and their robustness to experimental variations

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 204-219, January 2026.
Abstract Purpose Rotational invariants (RIs) are at the root of many dMRI applications. Among others, they are presented as a sensible way of reducing the dimensionality of biophysical models. While thermal noise impact on diffusion metrics has been well studied, little is known on its effect on spherical harmonics‐based RI (RISH) features and derived ...
