Solitary waves in fluid-filled elastic tubes: weakly dispersive case
(Pergamon-Elsevier Science, 2001-03)In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and the approximate equations of an incompressible inviscid fluid, the propagation of weakly nonlinear waves, in ... -
Some boundary Harnack principles with uniform constants
(Springer Science and Business Media B.V., 2022-10)We prove two versions of a boundary Harnack principle in which the constants do not depend on the domain by using probabilistic methods. -
Some inequalities which hold for starlike log-harmonic mappings of order alpha
(Eudoxus Press, LLC., 2014-04)Let H(D) be the linear space of all analytic functions defined on the open disc D = {z vertical bar vertical bar z vertical bar < 1}. A log-harmonic mappings is a solution of the nonlinear elliptic partial differential ... -
Some notes on spectra of cographs
(Charles Babbage Res Ctr, 2011-07)A cograph is a P-4-free graph. We first give a short proof of the fact that 0 (-1) belongs to the spectrum of a connected cograph (with at least two vertices) if and only if it contains duplicate (resp. coduplicate) vertices. ... -
Some properties concerning close-to-convexity of certain analytic functions
(Springer International Publishing AG, 2012)Let f(z) be an analytic function in the open unit disk D normalized with f(0) = 0 and f'(0) = 1. With the help of subordinations, for convex functions f(z) in D, the order of close-to-convexity for f(z) is discussed with ... -
