Uniform Bounds for Invariant Subspace Perturbations [PDF]
29 pages, 3 figures; added new theorem for random E; corrected typos and improved clarity; mild revisions to the way the main results are stated, but no significant changes to the results ...

Renormalization approach to the superconducting Kondo model
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.

Uniform Linear Bound in Chevalley's Lemma [PDF]
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.

Optimal PAC Bounds without Uniform Convergence
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]
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 (

Uniform derandomization from pathetic lower bounds [PDF]
The notion of probabilistic computation dates back at least to Turing, who also wrestled with the practical problems of how to implement probabilistic algorithms on machines with, at best, very limited access to randomness. A more recent line of research, known as derandomization, studies the extent to which randomness is superfluous.

Cheeger constants and $L^2$-Betti numbers [PDF]
We prove the existence of positive lower bounds on the Cheeger constants of manifolds of the form $X/\Gamma$ where $X$ is a contractible Riemannian manifold and ...

Quantitative Stability of Optimization Problems with Stochastic Constraints
In this paper, we consider optimization problems with stochastic constraints. We derive quantitative stability results for the optimal value function, the optimal solution set and the feasible solution set of optimization models in which the underlying ...

In this paper, we obtain a sharp upper bound on the spectral radius of a nonnegative k-uniform tensor and characterize when this bound is achieved. Furthermore, this result deduces the main result in [X. Duan and B.

A non-uniform bound on binomial approximation to the beta binomial cumulative distribution function [PDF]
This paper uses Stein’s method and the characterization of beta binomial random variable to determine a non-uniform bound for the distance between the beta binomial cumulative distribution function with parameters n N, 0 and 0 and the ...
