Homogeneity of dynamically defined wild knots [PDF]

open access: yes, 2005
In this paper we prove that a wild knot $K$ which is the limit set of a Kleinian group acting conformally on the unit 3-sphere, with its standard metric, is homogeneous: given two points $p, q\in{K}$ there exists a homeomorphism $f$ of the sphere such ...

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 ...

Large Scale Inhomogeneity Versus Source Evolution -- Can We Distinguish Them Observationally? [PDF]

open access: yes, 1997
We reconsider the issue of proving large scale spatial homogeneity of the universe, given isotropic observations about us and the possibility of source evolution both in numbers and luminosities.

“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

Homogeneous bands [PDF]

open access: yesAdvances in Mathematics, 2018
A countable band $B$ is called homogeneous if every isomorphism between finitely generated subbands extends to an automorphism of $B$. In this paper we give a complete classification of all the homogeneous bands. We prove that a homogeneous band belongs to the variety of regular bands, and has a homogeneous structure semilattice.
