Fractional Liouville equation on lattice phase-space

•Liouville equation for lattice phase-space with long-range jumps is suggested.•Continuous limit of lattice Liouville equation gives fractional Liouville equation.•Fractional Liouville equation is used to describe media with power-law nonlocality.

In this paper we propose a lattice analog of phase-space fractional Liouville equation. The Liouville equation for phase-space lattice with long-range jumps of power-law types is suggested. We prove that the continuum limit transforms this lattice equation into Liouville equation with conjugate Riesz fractional derivatives of non-integer orders with respect to coordinates of continuum phase-space. An application of the fractional Liouville equation with these Riesz fractional derivatives to describe properties of plasma-like nonlocal media is considered.
