We plan to talk about boundedness of Riesz transforms and multipliers associated to the Grushin operator $-\Delta-|x|^2 \partial_t^2$ on $\R^{n+1}$. We also discuss $L^p$ estimates for the wave equation associated to the Grushin operator. The main idea is to view Grushin multipliers as operator valued multipliers for the Euclidean Fourier transform.
