Abstract

In this paper, we present new conditions for the oscillation of all solutions of the third-order functional difference equations with semi-canonical operators by transforming the studied equation into canonical type equations. This greatly simplifies to find conditions for the oscillation of all solutions of the studied equation. The results obtained here essentially improve and complement to the ones in Srinivasan et al. (2022). The importance and the novelty of the findings are illustrated with five specific examples.
