Regular Homomorphisms and Regular Maps

open access: yesEuropean Journal of Combinatorics, 2002
AbstractRegular homomorphisms of oriented maps essentially arise from a factorization by a subgroup of automorphisms. This kind of map homomorphism is studied in detail, and generalized to the case when the induced homomorphism of the underlying graphs is not valency preserving.

Hadamard regularization [PDF]

open access: yesJournal of Mathematical Physics, 2000
Motivated by the problem of the dynamics of point-particles in high post-Newtonian (e.g., 3PN) approximations of general relativity, we consider a certain class of functions which are smooth except at some isolated points around which they admit a power-like singular expansion.

Renormalising SPDEs in regularity structures [PDF]

open access: yes, 2017
The formalism recently introduced in arXiv:1610.08468 allows one to assign a regularity structure, as well as a corresponding "renormalisation group", to any subcritical system of semilinear stochastic PDEs. Under very mild additional assumptions, it was

A Fourier Analysis Based New Look at Integration

open access: yesAnnales Mathematicae Silesianae, 2023
We approach the problem of integration for rough integrands and integrators, typically representing trajectories of stochastic processes possessing only some Hölder regularity of possibly low order, in the framework of para-control calculus.

Commentary on "A Computational Approach to the Detection and Prediction of (Ir)Regularity in Children's Folk Songs"

open access: yesEmpirical Musicology Review, 2023
This commentary on "A Computational Approach to the Detection and Prediction of (Ir)Regularity in Children's Folk Songs" by Mihelač, Povoh, and Wiggins reflects on the use of methods of (statistical) expectation to analyze musical structure and ...

Regularity of eigenstates in regular Mourre theory

open access: yesJournal of Functional Analysis, 2011
The present paper gives an abstract method to prove that possibly embedded eigenstates of a self-adjoint operator $H$ lie in the domain of the $k^{th}$ power of a conjugate operator $A$. Conjugate means here that $H$ and $A$ have a positive commutator locally near the relevant eigenvalue in the sense of Mourre.

Contact interaction of multilayer slabs with an inhomogeneous base

open access: yesMagazine of Civil Engineering, 2022
The article is devoted to the development of mathematical models and new methods for solving contact problems of multilayer elements of structures with an inhomogeneous base, considering their mechanical, structural features, and to the assessment of ...

A Fractional Laplace Equation: Regularity of Solutions and Finite Element Approximations [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2015
This paper deals with the integral version of the Dirichlet homogeneous fractional Laplace equation. For this problem weighted and fractional Sobolev a priori estimates are provided in terms of the Holder regularity of the data.

Edge-regular graphs with regular cliques [PDF]

open access: yesEuropean Journal of Combinatorics, 2018
We exhibit infinitely many examples of edge-regular graphs that have regular cliques and that are not strongly regular. This answers a question of Neumaier from 1981.

Q fever outbreak in the terraced vineyards of Lavaux, Switzerland

open access: yesNew Microbes and New Infections, EarlyView., 2014
Abstract Coxiella burnetii infection (Q fever) is a widespread zoonosis with low endemicity in Switzerland, therefore no mandatory public report was required. A cluster of initially ten human cases of acute Q fever infections characterized by prolonged fever, asthenia and mild hepatitis occurred in 2012 in the terraced vineyard of Lavaux ...
