, 2022 We study supervised learning problems that have significant effects on individuals from two demographic groups, and we seek predictors that are fair with respect to a group fairness criterion such as statistical parity (SP). A predictor is SP-fair if the distributions of predictions within the two groups are close in Kolmogorov distance, and fairness ...

Deformations of Anosov subgroups: Limit cones and growth indicators
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract Let G$G$ be a connected semisimple real algebraic group. We prove that limit cones vary continuously under deformations of Anosov subgroups of G$G$ under a certain convexity assumption, which turns out to be necessary. We apply this result to the notion of sharpness for the action of a discrete subgroup on a non‐Riemannian homogeneous space ...

Metrizations of Projective Spaces [PDF]
Proceedings of the American Mathematical Society, 1957 A two-dimensional G-space,1 in which the geodesic through two distinct points is unique, is either homeomorphic to the plane E2 and all geodesics are isometric to a straight line, or it is homeomorphic to the projective plane p2 and all geodesics are isometric to the same circle, see [1, ??10 and 31]. Two problems arise in either case: (1) To determine

Metrizability of Adjunction Spaces [PDF]
Proceedings of the American Mathematical Society, 1970 In a recent conversation with E. A. Michael and D. Hyman the following natural question was raised: Are the M-spaces of Hyman (see Definition 3.1) metrizable whenever they are first countable? We will answer this question affirmatively. Indeed, we will prove the somewhat stronger result that the M-spaces of Hyman are metrizable whenever they are of ...

Affine analogues of the Sasaki-Shchepetilov connection
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2016 For two-dimensional manifold M with locally symmetric connection ∇ and with ∇-parallel volume element vol one can construct a flat connection on the vector bundle TM⊕E, where E is a trivial bundle.

Graphical models for topological groups: A case study on countable Stone spaces
Bulletin of the London Mathematical Society, Volume 57, Issue 8, Page 2311-2335, August 2025.Abstract By analogy with the Cayley graph of a group with respect to a finite generating set or the Cayley–Abels graph of a totally disconnected, locally compact group, we detail countable connected graphs associated to Polish groups that we term Cayley–Abels–Rosendal graphs.

Applied General Topology, 2013 All spaces here are Tychonoff spaces. The class AE(0) consists of those spaces which are absolute extensors for compact zero-dimensional spaces. We define and study here the subclass AE(0)rp, consisting of those spaces for which extensions of continuous ...

Metrizability of General ANR [PDF]
Proceedings of the American Mathematical Society, 1986 We show that every nonmetrizable ANR( P ) {\text {ANR(}}\mathcal {P}{\text {)}} contains a copy of a Tychonoff cube of uncountable weight. Hence, every finite dimensional ANR( P )

Compactly convex sets in linear topological spaces [PDF]
Математичні Студії, 2012 A convex subset $X$ of a~linear topological space is called{em compactly convex} if there is a~continuous compact-valuedmap $Phicolon Xoexp(X)$ such that$[x,y]subsetPhi(x)cupPhi(y)$ for all $x,yin X$.
