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 ...

On uniform regularity and strong regularity [PDF]

open access: yesOptimization, 2018
We investigate uniform versions of (metric) regularity and strong (metric) regularity on compact subsets of Banach spaces, in particular, along continuous paths. These two properties turn out to play a key role in analyzing path-following schemes for tracking a solution trajectory of a parametric generalized equation or, more generally, of a ...

Regular Ultrapowers at Regular Cardinals [PDF]

open access: yesNotre Dame Journal of Formal Logic, 2015
In earlier work of the second and third author the equivalence of a finite square principle square^fin_{lambda,D} with various model theoretic properties of structures of size lambda and regular ultrafilters was established. In this paper we investigate the principle square^fin_{lambda,D}, and thereby the above model theoretic properties, at a regular ...

On regular but not completely regular spaces [PDF]

open access: yesTopology and its Applications, 2019
We present how to obtain non-comparable regular but not completely regular spaces. We analyze a generalization of Mysior's example, extracting its underlying purely set-theoretic framework. This enables us to build simple counterexamples, using the Niemytzki plane, the Songefrey plane or Lusin gaps.

Star-regularity and regular completions [PDF]

open access: yesJournal of Pure and Applied Algebra, 2014
In this paper we establish a new characterisation of star-regular categories, using a property of internal reflexive graphs, which is suggested by a recent result due to O. Ngaha Ngaha and the first author. We show that this property is, in a suitable sense, invariant under regular completion of a category in the sense of A. Carboni and E. M.

Regular colorings in regular graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
An (r − 1, 1)-coloring of an r-regular graph G is an edge coloring (with arbitrarily many colors) such that each vertex is incident to r − 1 edges of one color and 1 edge of a different color. In this paper, we completely characterize all 4-regular pseudographs (graphs that may contain parallel edges and loops) which do not have a (3, 1)-coloring. Also,

Fractional regularization matrices for linear discrete ill-posed problems [PDF]

open access: yes, 2015
The numerical solution of linear discrete ill-posed problems typically requires regularization. Two of the most popular regularization methods are due to Tikhonov and Lavrentiev. These methods require the choice of a regularization matrix. Common choices

Non-perturbative regularization and renormalization: simple examples from non-relativistic quantum mechanics [PDF]

open access: yes, 1997
We examine several zero-range potentials in non-relativistic quantum mechanics. The study of such potentials requires regularization and renormalization.

Regular updating [PDF]

open access: yesTheory and Decision, 2010
We study the Full Bayesian Updating rule for convex capacities. Following a route suggested by Jaffray (IEEE Transactions on Systems, Man and Cybernetics 22(5):1144–1152, 1992), we define some properties one may want to impose on the updating process, and identify the classes of (convex and strictly positive) capacities that satisfy these properties ...

Regularization matrices determined by matrix nearness problems [PDF]

open access: yes, 2016
This paper is concerned with the solution of large-scale linear discrete ill-posed problems with error-contaminated data. Tikhonov regularization is a popular approach to determine meaningful approximate solutions of such problems.
