Hyers-Ulam stability of first-order homogeneous linear differential equations with a real-valued coefficient
This paper is concerned with the Hyers–Ulam stability of the first-order linear differential equation x′ − ax = 0, where a is a non-zero real number. The main purpose is to find an explicit solution x(t) of x′−ax = 0 satisfying |φ(t)−x(t)| ≤ ε/|a| for all t ∈ R under the assumption that a differentiable function φ(t) satisfies |φ′(t)− aφ(t)| ≤ ε for all t ∈ R. In addition, the precise behavior ...

متن کاملCritical Oscillation Constant for Difference Equations with Almost Periodic Coefficients
and Applied Analysis 3 is conditionally oscillatory with the oscillation constant K 1/4. It is known see 22 that the equation [ r t y′ t ]′ γs t t2 y t 0, 1.5 where r, s are positive periodic continuous functions, is conditionally oscillatory as well. We also refer to 23 and 24–29 which generalize 23 for the discrete case, see 30 . Since the Euler difference equation Δyk γ k 1 k yk 1 0 1.6 is c...
متن کاملNecessary and sufficient conditions for oscillations of first order neutral delay difference equations with constant coefficients
In this paper, we establish the necessary and sufficient conditions for oscillation of the following first order neutral delay difference equation ∆[x(n) + px(n− τ)] + qx(n− σ) = 0, n ≥ n0, (∗) where τ and σ are positive integers, p 6= 0 is a real number and q is a positive real number. We proved that every solution of (∗) oscillates if and only if its characteristic equation (λ− 1)(1 + pλ−τ ) ...
