Strongly extreme points and approximation properties [PDF]
, 2017 We show that if $x$ is a strongly extreme point of a bounded closed convex subset of a Banach space and the identity has a geometrically and topologically good enough local approximation at $x$, then $x$ is already a denting point. It turns out that such

Extremal Steering Assemblages [PDF]
, 2021 Non-local correlations between a fully characterised quantum system and an untrusted black box device are described by an assemblage of conditional quantum states. These assemblages form a convex set, whose extremal points are relevant in many operational contexts.

Questions About Extreme Points
Integral Equations and Operator Theory, 2023 AbstractWe discuss the geometry of the unit ball—specifically, the structure of its extreme points (if any)—in subspaces of$$L^1$$L1and$$L^\infty $$L∞on the circle that are formed by functions with prescribed spectral gaps. A similar issue is considered for kernels of Toeplitz operators in$$H^\infty $$H∞.

Extreme purifying selection against point mutations in the human genome
Nature Communications, 2022 Previous work has investigated selection in the coding genome, but it is not as well characterized in the non-coding genome. By analyzing rare variants in 70k genome sequences from gnomAD, the authors detect very strong purifying selection ...

Global Structure of a Black-Hole Cosmos and its Extremes [PDF]
, 1993 We analyze the global structure of a family of Einstein-Maxwell solutions parametrized by mass, charge and cosmological constant. In a qualitative classification there are: (i) generic black-hole solutions, describing a Wheeler wormhole in a closed ...

New Rotation Sets in a Family of Torus Homeomorphisms [PDF]
, 2015 We construct a family $\{\Phi_t\}_{t\in[0,1]}$ of homeomorphisms of the two-torus isotopic to the identity, for which all of the rotation sets $\rho(\Phi_t)$ can be described explicitly.

Studying the Effect of Changes in Dew Point Temperature on Extreme Precipitation in the North West of Iran [PDF]
Nīvār, 2023 In the present research, using the daily precipitation data of 479 meteorological and rain gauge stations in the north west of Iran, the relationship between the changes in the dew point temperature and the precipitation in this region was investigated ...

𝐻¹ subordination and extreme points [PDF]
Proceedings of the American Mathematical Society, 1985 Suppose that F F is an element of H 1 {H^1} (Hardy class of order 1 over the unit disc). Let s ( F ) {\text {s}}(F) denote the set of functions subordinate to F F . We show that if ϕ \phi

Extremal correlations of the tripartite no-signaling polytope [PDF]
J. Phys. A: Math. Theor. 44, 065303 (2011), 2011 The no-signaling polytope associated to a Bell scenario with three parties, two inputs, and two outputs is found to have 53856 extremal points, belonging to 46 inequivalent classes. We provide a classification of these points according to various definitions of multipartite non-locality and briefly discuss other issues like the interconversion between ...
