<h4>The effect of linear perturbations on the Yamabe problem
</h4>
<h4><span style="font-style: italic;"></span>
In conformal geometry, the Compactness Conjecture asserts that the
set of Yamabe metrics on a smooth, compact, spherical Riemannian
manifold (M,g) is compact. Established in the locally conformally
flat case and for $n\leq 24$, it has revealed to be generally
false for $n\geq 25$. A stronger version of it, i.e. the
compactness under perturbations of the Yamabe equation, is
addressed with respect to the linear geometric potential. We show
that a-priori $L^\infty$--bounds or $H_1^2$--bounds fail in a very
general way under linear perturbations, and the results are
essentially optimal. Joint work with A. Pistoia and J. Vetois.
