Expansivity Property for Composition Operators on Orlicz -Lorentz Spaces

In this paper, we investige the concept of expansivity for composition operators on Orlicz-Lorentz spaces. We study necessary and sufficient conditions for expansivity, positive expansivity and uniformly expansivity for composition operators $C_{\tau }$ on ${\mathbb{L}}^{\phi ,h}(\mu )$. We extend the of results of [15] into Orlicz-Lorentz spaces
