# Fundamental solutions for wave equation in Robertson-Walker model of universe and $L^p-L^q$ -decay estimates

• We use constructed in [24] the fundamental solutions of the wave equation arising in the Robertson-Walker model of universe to derive the $L^p-L^q$-decay estimates for the solutions of the equation with and without a source term.
