Subordination Families and Extreme Points [PDF]
Transactions of the American Mathematical Society, 1988 Let s ( F ) s(F) denote the set of functions subordinate to a univalent function F F in Δ \Delta the unit disk. Let B 0 {B_0} denote the set of functions ϕ ( z ) \phi (z)

Analysis of temporal properties of wind extremes [PDF]
, 2018 The 10-minute average wind speed series recorded at 132 stations distributed rather homogeneously in the territory of Switzerland are investigated. Wind extremes are defined on the base of run theory: fixing a percentile-based threshold of the wind speed distribution, a wind extreme is defined as a sequence of consecutive wind values (or duration of ...

Regular points of extremal subsets in Alexandrov spaces [PDF]
J. Math Soc. Japan 74 (2022), no. 4, 1245-1268, 2019 We define regular points of an extremal subset in an Alexandrov space and study their basic properties. We show that a neighborhood of a regular point in an extremal subset is almost isometric to an open subset in Euclidean space and that the set of regular points in an extremal subset has full measure and is dense in it.

Extreme value and Haar series estimates of point process boundaries [PDF]
, 2011 We present a new method for estimating the edge of a two-dimensional bounded set, given a finite random set of points drawn from the interior. The estimator is based both on Haar series and extreme values of the point process.

Large deviations for point processes based on stationary sequences with heavy tails
, 2009 In this paper we propose a framework that enables the study of large deviations for point processes based on stationary sequences with regularly varying tails. This framework allows us to keep track not of the magnitude of the extreme values of a process,

Disorder effects at a nematic quantum critical point in d-wave cuprate superconductor
, 2011 A d-wave high temperature cuprate superconductor exhibits a nematic ordering transition at zero temperature. Near the quantum critical point, the coupling between gapless nodal quasiparticles and nematic order parameter fluctuation can result in unusual ...

Extreme points and optimal measures
Linear Algebra and its Applications, 2009 AbstractWe provide a new and more efficient proof of our earlier result that every 2×2 Toeplitz matrix M has a representing measure μ that is optimal in the sense that ‖μ‖=‖M‖S, the norm of M as a Schur multiplier. This result is seen to follow from some elementary observations about extreme points in the unit ball of trigonometric trinomials.

Operational extreme points of unital completely positive maps [PDF]
arXiv, 2016 Two notions for linear maps (operational convex combinations and operational exetreme points) are introduced. The set S of ucp maps on the n times n matrix algebra is the operational convex combinations of the identity map. An operational extreme point of S is an extreme point of S but the converse does not hold, and every automorphism is an ...
