Homogenous rivers, homogenous faunas [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
Habitat change and invasions of alien species are usually listed as the two biggest causes of biodiversity loss. When the two coincide, the results can be devastating, because altered habitat often favors alien species adapted to the changed conditions.

Mediated homogenization [PDF]

open access: yesPhysical Review A, 2007
Homogenization protocols model the quantum mechanical evolution of a system to a fixed state independently from its initial configuration by repeatedly coupling it with a collection of identical ancillas. Here we analyze these protocols within the formalism of "relaxing" channels providing an easy to check sufficient condition for homogenization.

Error estimates and convergence rates for the stochastic homogenization of Hamilton-Jacobi equations [PDF]

open access: yes, 2013
We present exponential error estimates and demonstrate an algebraic convergence rate for the homogenization of level-set convex Hamilton-Jacobi equations in i.i.d.

On cell problems for Hamilton-Jacobi equations with non-coercive Hamiltonians and its application to homogenization problems [PDF]

open access: yes, 2015
We study a cell problem arising in homogenization for a Hamilton-Jacobi equation whose Hamiltonian is not coercive. We introduce a generalized notion of effective Hamiltonians by approximating the equation and characterize the solvability of the cell ...

Homogenization of variational problems in manifold valued Sobolev spaces [PDF]

open access: yes, 2008
Homogenization of integral functionals is studied under the constraint that admissible maps have to take their values into a given smooth manifold.

Homogeneous algebras

open access: yesJournal of Algebra, 2003
Various concepts associated with quadratic algebras admit natural generalizations when the quadratic algebras are replaced by graded algebras which are finitely generated in degree 1 with homogeneous relations of degree N. Such algebras are referred to as {\sl homogeneous algebras of degree N}.

Homogeneity Pursuit [PDF]

open access: yesJournal of the American Statistical Association, 2015
This paper explores the homogeneity of coefficients in high-dimensional regression, which extends the sparsity concept and is more general and suitable for many applications. Homogeneity arises when regression coefficients corresponding to neighboring geographical regions or a similar cluster of covariates are expected to be approximately the same ...

Homogenization on arbitrary manifolds [PDF]

open access: yes, 2014
We describe a setting for homogenization of convex hamiltonians on abelian covers of any compact manifold. In this context we also provide a simple variational proof of standard homogenization results.Comment: 17 pages, 1 ...

“Homogenization with non‐homogeneous plastic flow”

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, 2023
AbstractThis paper provides the solution of a homogenization model that simultaneously considers the plastic and elastic strain fields in a single analytical formulation. In addition, the authors aim to decouple plastic flows triggered in the inclusions, in the matrix at the interfaces with the inclusions, and in the matrix at a large distance from the
