Nondegeneracy of Nonradial Nodal Solutions to Yamabe Problem

We provide the first example of a sequence of {\em nondegenerate}, in the sense of Duyckaerts-Kenig-Merle \cite{DKM}, nodal nonradial solutions to the critical Yamabe problem $$-\mathrm{\Delta }Q=\mathrm{\mid }Q{\mathrm{\mid }}^{\frac{2}{n-2}}Q,Q\in {\mathcal{D}}^{1,2}({\mathbb{R}}^n)\mathrm{.}$$
