From little string free energies towards modular graph functions
Journal of High Energy Physics, 2020 We study the structure of the non-perturbative free energy of a one-parameter class of little string theories (LSTs) of A-type in the so-called unrefined limit. These theories are engineered by N M5-branes probing a transverse flat space.

Nearby cycles of parahoric shtukas, and a fundamental lemma for base change
, 2020 Using the Langlands-Kottwitz paradigm, we compute the trace of Frobenius composed with Hecke operators on the cohomology of nearby cycles, at places of parahoric reduction, of perverse sheaves on certain moduli stacks of shtukas. Following an argument of

The biHecke monoid of a finite Coxeter group and its representations [PDF]
, 2012 For any finite Coxeter group W, we introduce two new objects: its cutting poset and its biHecke monoid. The cutting poset, constructed using a generalization of the notion of blocks in permutation matrices, almost forms a lattice on W.

JCMS: Journal of Common Market Studies, EarlyView.Abstract This study investigates how mainstream Europarties utilise social media to communicate with the public. According to EU law, Europarties are expected to strengthen the EU's legitimacy, mainly by fostering European political awareness and facilitating civic engagement.

Bounds for traces of Hecke operators and applications to modular and elliptic curves over a finite field [PDF]
, 2018 We give an upper bound for the trace of a Hecke operator acting on the space of holomorphic cusp forms with respect to certain congruence subgroups. Such an estimate has applications to the analytic theory of elliptic curves over a finite field, going ...

Modular Symbols and Hecke Operators [PDF]
, 2000 We survey techniques to compute the action of the Hecke operators on the cohomology of arithmetic groups. These techniques can be seen as generalizations in different directions of the classical modular symbol algorithm, due to Manin and Ash-Rudolph. Most of the work is contained in papers of the author and the author with Mark McConnell.

Hypergeometric motives from Euler integral representations
Journal 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 ...

Hecke-Clifford Algebras and Spin Hecke Algebras IV: Odd Double Affine Type
Symmetry, Integrability and Geometry: Methods and Applications, 2009 We introduce an odd double affine Hecke algebra (DaHa) generated by a classical Weyl group $W$ and two skew-polynomial subalgebras of anticommuting generators.

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

Agribusiness, 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.
