MATRIX POWER MEANS AND PÓLYA--SZEGÖ TYPE INEQUALITIES [PDF]

open access: yesSurveys in Mathematics and its Applications, 2020
t has been shown that if μ is a compactly supported probability measure on Mn+, then for every unit vector η∈ℂn, there exists a compactly supported probability measure (denoted by on ℝ+ so that the inequality ≤ Pt() (t∈(0,1]) holds. In particular,

A (p,q)-Averaged Hausdorff Distance for Arbitrary Measurable Sets

open access: yesMathematical and Computational Applications, 2018
The Hausdorff distance is a widely used tool to measure the distance between different sets. For the approximation of certain objects via stochastic search algorithms this distance is, however, of limited use as it punishes single outliers.
