The ball embedding property of the open unit disc
, 2011 We prove that the open unit disc Delta in C satisfies the ball embedding property in C(2); i.e., given any discrete set of discs in C(2) there exists a proper holomorphic embedding Delta hooked right arrow C(2) which passes arbitrarily close to the discs.

Unit ball in high dimensions [PDF]
, 2008 In this article, we compute the volume V n of the unit ball in an n-dimensional space. For n = 1, 2, 3, the volumes are respectively 2, π 4π /3, which are the length of interval [-1,1], area of a unit circle and volume of the unit sphere.

Radial 3D-Needlets on the Unit Ball [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractWe present a simple construction of spherical wavelets for the unit ball, which we label Radial 3D Needlets. We envisage an experimental framework where data are collected on concentric spheres with the same pixelization at different radial distances from the origin.

Stability of positive part of unit ball in Orlicz spaces [PDF]
, 2005 summary:The aim of this paper is to investigate the stability of the positive part of the unit ball in Orlicz spaces, endowed with the Luxemburg norm. The convex set $Q$ in a topological vector space is stable if the midpoint map $\Phi\colon Q\times Q ...

Touching graphs of unit balls [PDF]
, 1997 The touching graph of balls is a graph that admits a representation by non-intersecting balls in the space (of prescribed dimension), so that its edges correspond to touching pairs of balls. By a classical result of Koebe [5], the disc touching graphs are exactly the planar graphs. This paper deals with a recognition of unit-ball touching graphs. The 2-

On holomorphic isometric embeddings of the unit n-ball into products of two unit m-balls [PDF]
Mathematische Zeitschrift, 2010 Let \({\mathbb B}^n\) denote the unit ball in \({\mathbb C}^n\) equipped with the Bergman metric. The author considers a holomorphic embedding \(F(z)=\bigl(A(z),B(z)\bigr)\) from the product \({\mathbb B}^m\times {\mathbb B}^m\) into \({\mathbb B}^n\), isometric up to a normalization constant \(\lambda \). There are two trivial such embeddings: \(F_1(z)

Concentration of the distance between points in the unit ball [PDF]
, 1998 We prove that in every finite dimensional normed space, for “most” pairs (x, y) of points in the unit ball, ║x − y║ is more than √2(1 − ε). As a consequence, we obtain a result proved by Bourgain, using QS-decomposition, that guarantees an exponentially ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...
