Asymptotic Behavior of Positive Solutions of a Semilinear Dirichlet Problem outside the Unit Ball
نویسندگان
چکیده
In this article, we are concerned with the existence, uniqueness and asymptotic behavior of a positive classical solution to the semilinear boundaryvalue problem −∆u = a(x)u in D, lim |x|→1 u(x) = lim |x|→∞ u(x) = 0. Here D is the complement of the closed unit ball of Rn (n ≥ 3), σ < 1 and the function a is a nonnegative function in C loc(D), 0 < γ < 1, satisfying some appropriate assumptions related to Karamata regular variation theory.

The Dirichlet problem for supercritical biharmonic equations with power-type nonlinearity∗
For a semilinear biharmonic Dirichlet problem in the ball with supercritical power-type nonlinearity, we study existence/nonexistence, regularity and stability of radial positive minimal solutions. Moreover, qualitative properties, and in particular the precise asymptotic behaviour near x = 0 for (possibly existing) singular radial solutions, are deduced. Dynamical systems arguments and a suita...
متن کاملSymmetry Breaking for a Class of Semilinear Elliptic Problems
We study positive solutions of the Dirichlet problem for —Ají = up — A, p > 1, A > 0, on the unit ball 0. We show that there exists a positive solution (uo, Ao) of this problem which satisfies in addition duo/dn = 0 on âfî. We prove also that at (uo,Ao), the symmetry breaks, i.e. asymmetric solutions bifurcate from the positive radial solutions.
متن کاملInfinitely Many Radial Solutions for a Sub-Super Critical Dirichlet Boundary Value Problem in a Ball
We prove the existence of infinitely many solutions to a semilinear Dirichlet boundary value problem in a ball for a nonlinearity g(u) that grows subcritically for u positive and supercritically for u negative.
متن کاملNon-radial Solutions with Orthogonal Subgroup Invariance for Semilinear Dirichlet Problems
A semilinear elliptic equation, −∆u = λf(u), is studied in a ball with the Dirichlet boundary condition. For a closed subgroup G of the orthogonal group, it is proved that the number of non-radial G invariant solutions diverges to infinity as λ tends to ∞ if G is not transitive on the unit sphere.
متن کاملEntire Solutions for a Semilinear Fourth Order Elliptic Problem with Exponential Nonlinearity∗
We investigate entire radial solutions of the semilinear biharmonic equation ∆u = λ exp(u) in Rn, n ≥ 5, λ > 0 being a parameter. We show that singular radial solutions of the corresponding Dirichlet problem in the unit ball cannot be extended as solutions of the equation to the whole of Rn. In particular, they cannot be expanded as power series in the natural variable s = log |x|. Next, we pro...
