</b><b>"Nondegeneracy of sign-changing solutions to Yamabe problem
and its applications"</b><b><br>
</b><b>We first establish the existence of a sequence of
nondegenerate, in the sense of Duyckaerts-Kenig-Merle, nodal
solutions to the critical Yamabe problem $$ -\Delta Q=
|Q|^{\frac{4}{N-2}} Q, Q \in D^{1,2}$$ Then we use it to
construct sign-changing bubbling solutions to the slightly
super-critical Bahri-Coron problem in a bounded domain with
nontrivial topology.</b></big><br>
