On The Kirchhoff Equation In The Whole Space R ~ N The Multiplicity Of Solutions Of The Radial Symmetry

In this paper, we concern with a class of Kirchhof-type problems in RNwhere constants a, b>0, the nonlinearity f (x, u) is a continuous functional definedon RN×R. By using the Fountain Theorem we obtain four existence results ofinfinitely many radial solutions for the problem.
