On the stability of linear differential equations of second order
The aim of this paper is to investigate the Hyers-Ulam stability of the linear differential equation$$y''(x)+alpha y'(x)+beta y(x)=f(x)$$in general case, where $yin C^2[a,b],$ $fin C[a,b]$ and $-infty
متن کاملOscillation and Nonoscillation Criteria for Second-order Linear Differential Equations
Sufficient conditions for oscillation and nonoscillation of second-order linear equations are established. 1. Statement of the Problem and Formulation of Basic Results Consider the differential equation u′′ + p(t)u = 0, (1) where p : [0, +∞[→ [0, +∞[ is an integrable function. By a solution of equation (1) is understood a function u : [0,+∞[→] − ∞, +∞[ which is locally absolutely continuous tog...

For the second order linear impulsive differential equation with oscillatory coefficient ⎧⎨ ⎩ (r(t)x′(t))′ +h(t)x(t) = 0, t = tk, tk t0, k = 1,2, · · · , x(t+ k ) = akx(tk), x ′(t+ k ) = bkx ′(tk), k = 1,2, · · · , x(t+ 0 ) = x0, x ′(t+ 0 ) = x ′ 0, (E) where h can be changed sign on [t0,∞) , by using the equivalence transformation, we establish an associated impulsive differential equation wit...
متن کاملOscillation Criteria for Second-order Linear Differential Equations^)
where p(x) is a continuous positive function for 0<x< oo. Equation (1) is said to be nonoscillatory in (a, oo) if no solution of (1) vanishes more than once in this interval. Because of the Sturm separation theorem, this is equivalent to the existence of a solution which does not vanish at all in (a, oo). The equation will be called nonoscillatory—without the interval being mentioned —if there ...
متن کاملNecessary and Sufficient Condition for Oscillation of Higher Order Nonlinear Delay Difference Equations
-This paper is concerned with the oscillation of solutions of higher order nonlinear delay difference equations with forcing terms of the form Anx(t) + f(t, x(t),x(a(t))) = h(t), t E I = {0, 1 . . . . }, where A is the forward difference operator defined by Ax(t) = x(t + 1) -x(t) and A'nx(t) = A(Am-lx(t)), m > 1. A necessary and sufficient condition is established under which every solution x(t...
