The purpose of this paper is twofold.First,by using the hyperbolic metric,we establish the Bohr radius for analytic functions from shifted disks containing the unit disk D into convex proper domains of the complex plane.As a consequence,we generalize the Bohr radius of Evdoridis,Ponnusamy and Rasila based on geometric idea.By introducing an alternative multidimensional Bohr radius,the second purpose is to obtain the Bohr radius of higher dimensions for Carathéodory families in the unit ball B of a complex Banach space X.Notice that when B is the unit ball of the complex Hilbert space X,we show that the constant 1/3 is the Bohr radius for normalized convex mappings of B,which generalizes the result of convex functions on D. 展开更多

We evaluate three of the quantum constants of hydrogen, the electron, e<sup>-</sup>, the Bohr radius, a<sub>0</sub>, and the Rydberg constants, , as natural unit frequency equivalents, v. This is equivalent to Planck’s constant, h, the speed of light, c, and the electron charge, e, all scaled to 1 similar in concept to the Hartree atomic, and Planck units. These frequency ratios are analyzed as fundamental coupling constants. We recognize that the ratio of the product of 8π<sup>2</sup>, the v<sub>e</sub><sub>-</sub> times the v<sub>R</sub> divided by v<sub>a</sub><sub>0</sub> squared equals 1. This is a power law defining Planck’s constant in a dimensionless domain as 1. We also find that all of the possible dimensionless and dimensioned ratios correspond to other constants or classic relationships, and are systematically inter-related by multiple power laws to the fine structure constant, α;and the geometric factors 2, and π. One is related to an angular momentum scaled by Planck’s constant, and another is the kinetic energy law. There are harmonic sinusoidal relationships based on 2π circle geometry. In the dimensionless domain, α is equivalent to the free space constant of permeability, and its reciprocal to permittivity. If any two quanta are known, all of the others can be derived within power laws. This demonstrates that 8π2 represents the logical geometric conversion factor that links the Euclid geometric factors/three dimensional space, and the quantum domain. We conclude that the relative scale and organization of many of the fundamental constants even beyond hydrogen are related to a unified power law system defined by only three physical quanta of v<sub>e</sub><sub>-</sub>, v<sub>R</sub>, and v<sub>a</sub><sub>0</sub>. 展开更多

In this paper,we mainly use the Frechet derivative to extend the Bohr inequality with a lacunary series to the higher-dimensional space,namely,mappings from Unto U(resp.Unto Un).In addition,we discuss whether or not there is a constant term in f,and we obtain two redefined Bohr inequalities in Un.Finally,we redefine the Bohr inequality of the odd and even terms of the analytic function f so as to obtain conclusions for two different higher-dimensional alternating series. 展开更多
