Abstract
GARCIA CAMACHO, GONZALO and POSADA VERA, LILIANA. Lq estimates of functions in the kernel of an elliptic operator and applications. Integración - UIS [online]. 2016, vol.34, n.1, pp.1-21. ISSN 0120-419X. https://doi.org/10.18273/revint.v34n1-2016001.
In this work, we will find a family of small functions ηy in the Kernel of an operator defined in the intersection of the Sobolev space H2,q(Sn) with the orthogonal complement in H1,2(Sn) of the first eigenspace of the laplacian on Sn, parameterized with a variable y belonging to a small ball contained in Bn+1. We will find Lq estimates of these functions and we will use those estimates to find a subcritical solution to the scalar curvature problem on Sn, and a solution of a nonlinear elliptical problem related to that problem, where Fy1 : Sn→ Sn is a centered dilation.
Keywords : Sobolev spaces; conformal deformations; elliptic equations.
