Distortion Type Theorems for Functions in the Logarithmic Bloch Space

open access: yesJournal of Function Spaces, 2017
We establish distortion type theorems for locally schlicht functions and for functions having branch points satisfying a normalized Bloch condition in the closed unit ball of the logarithmic Bloch space Blog.

Extensions of Hénon maps to the closed 4-ball [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2000
Any polynomial automorphism of $\mathbb{C}^2$ with nontrivial dynamics is conjugate to a diffeomorphism of the 4-ball such that this diffeomorphism extends to a diffeomorphism of the closed 4-ball. Moreover, the conjugating map is a smooth bijection of $\mathbb{C}^2$ to itself.

Scale up and simulation of Vertimill™ pilot test operated with copper ore

open access: yesJournal of Materials Research and Technology, 2014
Vertimill™ has been used in regrind circuits during the past years due to its greater efficiency when compared to the conventional tube ball mill. This paper presents the Vertimill™ pilot grinding tests with a sample of copper ore carried out in closed ...

Characterizations of inner product spaces by orthogonal vectors

open access: yesJournal of Function Spaces and Applications, 2006
Let X be a real normed space with unit closed ball B. We prove that X is an inner product space if and only if it is true that whenever x, y are points in ?B such that the line through x and y supports 22B then x?y in the sense of Birkhoff.

A concave holomorphic filling of an overtwisted contact $3$-sphere

open access: yes, 2018
In this paper we prove that the closed $4$-ball admits non-K\"ahler complex structures with strictly pseudoconcave boundary. Moreover, the induced contact structure on the boundary $3$-sphere is overtwisted.Comment: 11 pages, 0 ...

On the compactness of the set of L-2 trajectories of the control system

open access: yesNonlinear Analysis, 2018
In this paper, the compactness of the set of L2 trajectories of the control system described by the Urysohn-type integral equation is studied. The control functions are chosen from the closed ball of the space L2 with radius r and centered at the origin.

Analytic functions over valued fields

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
Let K be a non-archimedean, non-trivially (rank 1) valued complete field. B, B0 denote the closed and open unit ball of K respectively. Necessary and sufficient conditions for analytic functions defined on B, B0 with values in K to be injective ...
