✦ Synopsis
We consider the inequality u t ≥ u -1 2 x • ∇u + λu + h x t u p , for p > 1 λ ∈ , posed in N × + N ≥ 1. We show that, in certain growth conditions, there is an absence of global weak solutions.

are presented. The proofs are based on the alternative method, a connectedness result, the contraction mapping principle, and a detailed analysis of the bifurcation equation utilizing, e.g., a generalization of the mean value theorem for integrals. We shall obtain results with g bounded or unbounded
where λ > 0 is a parameter and T > 0 is a constant. It is known that if λ 1, then the corresponding solution has boundary layers. In this paper, we characterize λ by the boundary layers of the solution when λ 1 from a variational point of view. To this end, we parameterize a solution pair λ u by a n
