On the Existence of Positive Entire Solutions of a Semilinear Elliptic Equation

  • Chapter
Analysis and Continuum Mechanics

Abstract

Under suitable hypotheses we obtain various theorems concerning the existence of positive solutions of the equation

$$artriangle u - u + Qeft( x ight){u^p} = 0$$

in ℝn, where p >1 and Q(x) is a given potential. If Q is radially symmetric, our result is particularly simple and general. We also study symmetries of solutions of the above equation in a ball with the boundary condition u = 0.
