On a Logistic Differential Model. Some Applications

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...

Some applications of differential subordination

A number of interesting criteria were given by earlier workers for a normalized analytic function to be in the familiar class ∗ of starlike functions. The main object of the present paper is to extend and improve each of these earlier results. An application associated with an integral operator c(c >−1) is also considered.

Some Results on Differential Equations and Their Applications.

&(U) also becomes a Banach space. If p(t) = Eu(k)tk (u(k)EU, k e Z+1) is a Uk polynomial, we define IIpI = u(k) I. k Let C+I denote the set of all points t E Cl such that Re ts > 0 (1 < i < 1). Put R+I= C+1lnRI. THEOREM 1. Let r, (1 < i < 1) be holomorphic functions on C+1 with values in 8(U). Suppose V is a nonempty connected open set in R+' and q a function on V with values in U, which satisf...

On some generalized discrete logistic maps

Recently, conventional logistic maps have been used in different vital applications like modeling and security. However, unfortunately the conventional logistic maps can tolerate only one changeable parameter. In this paper, three different generalized logistic maps are introduced with arbitrary powers which can be reduced to the conventional logistic map. The added parameter (arbitrary power) ...
