Abstract:

This paper studies the statistical solutions for the nonautonomous modified Swift-Hohenberg equation in weighted spaces. The authors first show the existence of pullback attractors of the process generated by this equation. Then the paper further establishes the existence of a unique family of invariant Borel probability measures carried by the pullback attractors, and finally prove that the family of invariant Borel probability measures is a statistical solution for this equation.

Key words: statistical solution, weighted space, discrete modified Swift-Hohenberg equation
