Nonexistence of Positive Supersolutions of Nonlinear Biharmonic Equations without the Maximum Principle Academic Article

abstract

• 2015, Taylor & Francis Group, LLC. We study classical positive solutions of the biharmonic inequality (Formula presented.) in exterior domains in ⁿ where f: (0, )(0, ) is continuous function. We give lower bounds on the growth of f(s) at s=0 and/or s = such that inequality (0.1) has no C⁴ positive solution in any exterior domain of ⁿ. Similar results were obtained by Armstrong and Sirakov for vf(v) using a method which depends only on properties related to the maximum principle. Since the maximum principle does not hold for the biharmonic operator, we adopt a different approach which relies on a new representation formula and an a priori pointwise bound for nonnegative solutions of ² u0 in a punctured neighborhood of the origin in ⁿ.
