Functional equations for zeta functions of groups and rings [PDF]
, 2010 We introduce a new method to compute explicit formulae for various zeta functions associated to groups and rings. The specific form of these formulae enables us to deduce local functional equations. More precisely, we prove local functional equations for

Product set growth in virtual subgroups of mapping class groups [PDF]
, 2023 We study product set growth in groups with acylindrical actions on quasi-trees and, more generally, hyperbolic spaces. As a consequence, we show that for every surface $S$ of finite type, there exist $\alpha,\beta>0$ such that for any finite symmetric ...

Acylindrical hyperbolicity of groups acting on trees [PDF]
, 2015 We provide new examples of acylindrically hyperbolic groups arising from actions on simplicial trees. In particular, we consider amalgamated products and HNN-extensions, 1-relator groups, automorphism groups of polynomial algebras, 3-manifold groups and ...

On the existence of isotropic forms of semi-simple algebraic groups over number fields with prescribed local behavior [PDF]
, 2006 This note is a follow-up on the paper [A. Borel, G. Harder, Existence of discrete cocompact subgroups of reductive groups over local fields, J. Reine Angew. Math. 298 (1978) 53–64] of A. Borel and G.

A Coarse Geometric Approach to Graph Layout Problems
Journal of Graph Theory, EarlyView.ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

Negative symbolism of wildlife shapes human–nature coexistence: The plight of owls in Nigeria
People and Nature, EarlyView.Abstract Human–wildlife coexistence in culturally diverse landscapes requires understanding how socio‐cultural processes shape perceptions and behaviours towards conservation‐priority species. This study examines perceptions, belief‐based uses and conservation attitudes towards owls in communities surrounding six Protected Areas in Nigeria, addressing ...

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This article proposes a distributed resilient control framework to ensure consensus tracking for nonlinear heterogeneous multi‐agent systems (NHMAS) under aperiodic denial‐of‐service (DoS) attacks. First, a resilient observer is introduced to estimate the leader's state considering that not all agents have direct access to the leader's ...

A tutorial on Bayesian model averaging for exponential random graph models
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...

Representation growth and rational singularities of the moduli space of local systems [PDF]
, 2013 Let G be a semisimple algebraic group defined over Qp, and let Γ be a compact open subgroup of G(Qp). We relate the asymptotic representation theory of Γ and the singularities of the moduli space of G-local systems on a smooth projective curve, proving ...

Universalism: an 11‐year longitudinal study
Economica, EarlyView.Abstract How individuals make trade‐offs between socially proximate or distant groups impacts upon a wide range of social, political and economic behaviours. This paper exploits Norwegian administrative register data over the 2012–2022 period to assess whether, and if so how, such ‘(moral) universalism’ develops as individuals age and go through major ...
