m-Bounded Uniformities Between Two Given Uniformities [PDF]

open access: yesTransactions of the American Mathematical Society, 1969
Introduction. This paper is an attempt to gain some information about the lattice of the uniformities which can be defined on a set X. Our results are stated in terms of the m-boundedness of uniformities, where m is an infinite cardinal. We define a pseudo-metric p on X to be m-bounded if for e > 0, X can be written as a union of fewer than m sets ...

Uniform bounds for isoperimetric problems [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
In this paper we generalize our previous joint work with Allan Calder on the width of homotopies by considering an arbitrary finite polyhedral pair ( W , V ) \left ( {W,V} \right ) rather than ( I , {

Uniform Linear Bound in Chevalley's Lemma [PDF]

open access: yesCanadian Journal of Mathematics, 2008
AbstractWe obtain a uniform linear bound for the Chevalley function at a point in the source of an analytic mapping that is regular in the sense of Gabrielov. There is a version of Chevalley’s lemma also along a fibre, or at a point of the image of a proper analytic mapping.

Renormalization approach to the superconducting Kondo model

open access: yesSciPost Physics, 2022
An approach to bound states based on unitary transformations of Hamiltonians is presented. The method is applied to study the interaction between electrons in a BCS $s$-wave superconductor and a quantum spin.

Optimal PAC Bounds without Uniform Convergence

open access: yes2023 IEEE 64th Annual Symposium on Foundations of Computer Science (FOCS), 2023
In statistical learning theory, determining the sample complexity of realizable binary classification for VC classes was a long-standing open problem. The results of Simon and Hanneke established sharp upper bounds in this setting. However, the reliance of their argument on the uniform convergence principle limits its applicability to more general ...

Uniform bounds for strongly 𝐹-regular surfaces [PDF]

open access: yesTransactions of the American Mathematical Society, 2015
We show that if ( X , B ) (X,B) is a two dimensional Kawamata log terminal pair defined over an algebraically closed field of characteristic p p , and p p is sufficiently large, depending only on the coefficients of B B , then (
