  • HYERS-ULAM STABILITY OF THE LINEAR RECURRENCE WITH CONSTANT COEFFICIENTS DORIAN POPA Received 5 November 2004 and in revised form 14 March 2005 Let X be a Banach space over the field R or C, a1 ,...,a p ∈ C, and (bn )n≥0 a sequence in X. We investigate the Hyers-Ulam stability of the linear recurrence xn+p = a1 xn+p−1 + · · · + a p−1 xn+1 + a p xn + bn , n ≥ 0, where x0 ,x1 ,...,x p−1 ∈ X. 1. Introduction In 1940, S. M. Ulam proposed the following problem. Problem 1.1. Given a metric group (G,...

  • This is the eighth book containing examples from the Theory of Complex Functions. In this volume we show how we can apply the calculations of residues in connection with some classical transforms like the Laplace transform, the Mellin transform, the z-transform and the Fourier transform. I have further supplied with some examples from the Theory of Linear Difference Equations and from the Theory of Distributions, also called generalized functions.

  • In this paper, we present a method for determining complex permittivity of materials using two different thicknesses of the sample placed in free space. The proposed method is based on the use of transmission having the same geometry with different thicknesses with the aim to determine the complex propagation constant (γ). The reflection and transmission coefficients (S11 and S21) of material samples are determined using a free-space measurement system.

  • This book is written for the practicing pharmaceutical scientist involved in absorption–distribution–metabolism–excretion (ADME) measurements who needs to communicate with medicinal chemists persuasively, so that newly synthesized molecules will be more ‘‘drug-like.’’ ADME is all about ‘‘a day in the life of a drug molecule’’ (absorption, distribution, metabolism, and excretion).

  • Anharmonic effective potential, effective local force constant, thermal expansion coefficient, three leading cumulants, and EXAFS (Extended X-ray Absorption Fine Structure) of hcp crystals have been studied. Analytical expressions for these quantities have been derived. Numerical calculations have been carried out for Zn and Cd. They show a good agreement with experiment results measured at HASYLAB (DESY, Germany) and unnegligible anharmonic effects in the considered quantities.
