On Lidstone Boundary Value Problem for Higher Order Nonlinear Hyperbolic Equations with Two Independent Variables
Moreover, below it will be assumed that the function f : D×R4mn → R is continuous, the functions φ2i : [0, b] → R, φ2i : [0, b] → R (i = 0, . . . ,m − 1) are 2n–times continuously differentiable, and the functions ψ2k : [0, a] → R, ψ2k : [0, a] → R (i = 0, . . . , n − 1) are continuous. By C2m,2n(D) denote the space of continuous functions u : D → R having the continuous partial derivatives u(j...
متن کاملOn the Reflection Laws of Second Order Differential Equations in Two Independent Variables
The main purpose of this paper is the study of the analytic continuation of solutions of elliptic differential equations in two independent variables across an analytic boundary on which they satisfy further analytic equations connecting the point of the boundary, the value of the solution and those of its first order partial derivatives. In its simplest form the problem is that of the continua...
متن کاملOn Fuzzy Solution for Exact Second Order Fuzzy Differential Equation
In the present paper, the analytical solution for an exact second order fuzzy initial value problem under generalized Hukuhara differentiability is obtained. First the solution of first order linear fuzzy differential equation under generalized Hukuhara differentiability is investigated using integration factor methods in two cases. The second based on the type of generalized Hukuhara different...
متن کاملA RESEARCH NOTE ON THE SECOND ORDER DIFFERENTIAL EQUATION
Let U(t, ) be solution of the Dirichlet problem y''+( t-q(t))y= 0 - 1 t l y(-l)= 0 = y(x), with variabIe t on (-1, x), for fixed x, which satisfies the initial condition U(-1, )=0 , (-1, )=1. In this paper, the asymptotic representation of the corresponding eigenfunctions of the eigen values has been investigated . Furthermore, the leading term of the asymptotic formula for ...
متن کاملOn Blow–up Solutions of Initial Characteristic Problem for Nonlinear Hyperbolic Systems with Two Independent Variables
Global solvability of the problem (1),(2) was studied rather thoroughly (see, e.g., [1– 9] and the literature quoted therein). In the present paper new sufficient conditions of existence and nonexistence of so called blow-up solutions to the problem (1),(2) are given. To formulate the main results, we need to introduce the following notation and definitions. z = (zi) n i=1 ∈ R n is a vector wit...
