Abstract: In this paper, we consider a type of fuzzy harmonic oscillator described by a differential equation of the form x″ + a2x = 0 with initial conditions given by fuzzy numbers. Here, we assume that x″ (t) and a2x (t) are linearly correlated fuzzy numbers for
t∈ℝ
and
a∈ℝ,a≠0
. In general, this assumption is necessary for the equality x″ + a2x = 0 to make sense. Using this interactive relation, we obtain a solution for this problem using a fuzzy Laplace transform method.
