Problema <strong>de</strong> Yamabe<br />

<strong>Hipersuperficies</strong> Isopara<strong>métricas</strong><br />

Resultados<br />

Vamos a mostrar resultados acerca <strong>de</strong> la multiplicidad <strong>de</strong> las<br />

soluciones a la ecuación <strong>de</strong> Yamabe para<br />

(S n × S k , [g n 0 + Tg k 0 ]) que <strong>de</strong>pen<strong>de</strong>n sólo <strong>de</strong> S n .<br />

− ∆g0u + λu = λuq<br />

con 2 < q = pn+k − 1 < pn − 1, λ =<br />

n(n−1)+(1/T )k(k−1)<br />

.<br />

an+k<br />

Veremos que existen soluciones no radiales.<br />

Caso radial: Jin, Li y Xu (2008) y Petean (2010).<br />

S ⊂ S n<br />

h. isoparamétrica<br />

existe f solución <strong>de</strong> (2) tal que f es constante en S × S k .<br />
