Existence of weak solutions for a boundary value problem of a second order ordinary differential equation
where the functions f , g : [0, 1]× R→ R and h : [0, 1]× R→ R\{0} satisfy some special assumptions that will be given in detail in Section 3. Boundary value problems arise in a variety of applied mathematics and physics areas (refer to [1, 2] etc.). Some boundary value problems of ordinary equations may be turned into (1.1)-(1.2). For example, in the design of bridge, denote u(t) by the displac...
متن کاملExistence of periodic solutions for a semilinear ordinary differential equation
Dancer [3] found a necessary and sufficient condition for the existence of periodic solutions to the equation ẍ+ g1(ẋ) + g0(x) = f(t) . His condition is based on a functional that depends on the solution to the above equation with g0 = 0. However, that solution is not always explicitly known which makes the condition unverifiable in practical situations. As an alternative, we find computable bo...
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 کاملExistence of positive solutions of the Cauchy problem for a second-order differential equation
In this paper we consider the equation u (t) = f (t, u(t), u (t)) and prove the unique solvability of the Cauchy problem u(0) = 0, u (0) = λ with λ > 0.
متن کاملSTUDYING THE BEHAVIOR OF SOLUTIONS OF A SECOND-ORDER RATIONAL DIFFERENCE EQUATION AND A RATIONAL SYSTEM
In this paper we investigate the behavior of solutions, stable and unstable of the solutions a second-order rational difference equation. Also we will discuss about the behavior of solutions a the rational system, we show these solutions may be stable or unstable.
