“…The corresponding eigenfunction ψ is simple and can be chosen such that ψ(x) > 0 for all x ∈ Ω and normalised such that ψ ∞ = 1. The proofs in [17] using the direct method in the calculus of variations are easily adapted to our situation (see [6,Section 2] or [16,Theorem 3.4]). Note that the very elegant and simple proof from [13,2] could be adapted.…”

“…In fact we can show that ui(z) •£ 0 almost everywhere on Z and so we can assume that U\ > 0 almost everywhere on Z. For details we refer to Lindqvist [11].…”

“…We denote (λ 1 (int(U )), φ 1 (int(U ))) the first eigenpair of −∆ p on int(U ) with zero Dirichlet boundary conditions. It is known that λ 1 (int(U )) is positive, simple and isolated, and φ 1 (int(U )) is positive [11]. To simplify notations, we write…”
