Existence and concentration of normalized solutions for p-Laplacian equations with logarithmic nonlinearity
arxiv(2024)
摘要
We investigate the existence and concentration of normalized solutions for a
p-Laplacian problem with logarithmic nonlinearity of type
{[ -ε^pΔ_p u+V(x)|u|^p-2u=λ
|u|^p-2u+|u|^p-2ulog|u|^p in ℝ^N,∫_ℝ^N|u|^pdx=a^pε^N, ].
where a,ε> 0, λ∈ℝ is known as the
Lagrange multiplier, Δ_p· =div (|∇·|^p-2∇·) denotes the usual p-Laplacian operator with 2≤ p < N and V ∈𝒞^0(ℝ^N) is the potential which satisfies some suitable
assumptions. We prove that the number of positive solutions depends on the
profile of V and each solution concentrates around its corresponding global
minimum point of V in the semiclassical limit when ε→0^+ using
variational method.
Moreover, we also get the existence of normalized solutions for some
logarithmic p-Laplacian equations involving mass-supercritical
nonlinearities.
