Higher Robin eigenvalues for the p-Laplacian operator as p approaches 1
This work addresses several aspects of the dependence on p of the higher eigenvalues λ n to the Robin problem, - Δ p u = λ | u | p - 2 u x ∈ Ω , | ∇ u | p - 2 ∂ u ∂ ν + b | u | p - 2 u = 0 x ∈ ∂ Ω . Here, Ω ⊂ R N is a C 1 bounded domain, ν is the outer unit normal, Δ p u = div ( | ∇ u | p - 2 ∇ u )...

. Main results concern: (a) the existence of the limits of
λ

as
p

, (b) the ‘limit problems’ satisfied by the ‘limit eigenpairs’, (c) the continuous dependence of
λ
n
on

when

and (d) the limit profile of the eigenfunctions as

. The latter study is performed in the one dimensional and radially symmetric cases. Corresponding properties on the Dirichlet and Neumann eigenvalues are also studied in these two special scenarios. |
