Web1 de jan. de 2024 · One can see that the second largest Laplacian eigenvalue of G ′ does not exceed 3, because if we add another vertex w adjacent to u and v, then again we have a Friendship graph, which by Lemma 5.3, its second largest Laplacian eigenvalue is 3. So the second largest Laplacian eigenvalue of G ′ does not exceed 3. Theorem 5.4 Web31 de mar. de 2016 · Published: July 2024. Abstract. The p -Laplacian operator Δ p u = d i v ( ∇ u p − 2 ∇ u) is not uniformly elliptic for any p ∈ ( 1, 2) ∪ ( 2, ∞) and degenerates even more when p → ∞ or p → 1. In those two cases the Dirichlet and eigenvalue problems associated with the p -Laplacian lead to intriguing geometric questions ...
