1. The Picone identity for a class of partial differential equations Creator: Došlý, Ondřej Format: bez média and svazek Type: model:article and TEXT Subject: Picone’s identity, half-linear PDE, p-Laplacian, and variational technique Language: English Description: The Picone-type identity for the half-linear second order partial differential equation n∑ i=1 ∂ ⁄ ∂xi Φ (∂u ⁄ ∂xi) + c(x)Φ(u) = 0, Φ(u) := |u| p−2 u, p > 1, is established and some applications of this identity are suggested.
