Abstract
The existence of three nontrivial solutions for a nonlinear problem on compact d-dimensional (d >= 3) Riemannian manifolds without boundary, is established. This multiplicity result is then applied to solve Emden-Fowler equations that involve sublinear terms at infinity. Two concrete examples are also provided in the present paper. Our results apply to problems arising in conformal Riemannian geometry, astrophysics, and in the theories of thermionic emission, isothermal stationary gas sphere, and gas combustion.File in questo prodotto:
