Comparison theorems for perturbed modified Euler type linear and half-linear differential equations
摘要
We establish two comparison theorems for modified Euler type linear and half-linear differential equations with perturbations in both terms. The presented comparison theorems imply the oscillation and non-oscillation of equations in the studied form applying previously known oscillation and non-oscillation criteria, respectively. Thus, we enlarge the set of analyzed equations whose oscillation behavior is known.
