Resumen de Multiple Solutions to a Transmission Problem with a Critical Hardy-Sobolev Exponential Source Term

Yue Wang

• In the paper there are established many results for a transmission problem with critical Hardy-Sobolev exponential source term u3 |x| in R3. We obtain that there are at least three weakly nontrivial solutions when a positive coefficient of nonhomogeneous term is enough small using the variational method. Next infinitely many classical solutions are obtained when the coefficient equals to zero. Moreover, a new compactness condition is derived with the help of Brezis-Lieb’s lemma and Mazur’s lemma.
