On K-peak solutions for the Yamabe equation on product manifolds

Juan Miguel Ruiz, Areli Vázquez Juárez

Let $(M^{n}, g)$ and $(X^{m}, h)$ be closed manifolds $m, n > 2$ , such that $(X, h)$ has constant positive scalar curvature. We consider the one parameter family of products $(M\times X,…

Isoperimetric estimates in the product of small and large volume manifolds

Juan Miguel Ruiz, Areli Vázquez Juárez

Let $(M^{m}, g)$ , $(N^{n}, h)$ be closed Riemannian manifolds, $m, n \geq 2$ , with concave isoperimetric profiles and volumes $V_{M}$ , $V_{N}$ respectively. We consider a one parameter family…

Lower bounds for isoperimetric profiles and Yamabe constants

Juan Miguel Ruiz, Areli Vázquez Juárez

We estimate explicit lower bounds for the isoperimetric profiles of the Riemannian product of a compact manifold and the Euclidean space with the flat metric, $(M^m\times \mathbb{R…

Isoperimetric estimates in low dimensional Riemannian products

Juan Miguel Ruiz, Areli Vazquez Juarez

Let $(T^{k}, h_{k}) = (S_{r_{1}}^{1} \times S_{r_{2}}^{1} \times ... \times S_{r_{k}}^{1}, d t_{1}^{2} + d t_{2}^{2} + ... + d t_{k}^{2})$ be flat tori, $r_{k} \geq ... \geq r_{2} \geq r_{1} > 0$ and $(R^{n}, g_{E})$ the Euclidea…

Stable solutions of the Yamabe equation on non-compact manifolds

Jimmy Petean, Juan Miguel Ruiz

We consider the Yamabe equation on a complete non-compact Riemannian manifold and study the condition of stability of solutions. If $(M^{m}, g)$ is a closed manifold of constant posit…

Isoperimetric profile comparisons and Yamabe constants

Jimmy Petean, Juan Miguel Ruiz

We estimate from below the isoperimetric profile of $S^2 \times \re^2$ and use this information to obtain lower bounds for the Yamabe constant of $S^2 \times \re^2$. This provides…
