1. Hartman-Wintner type criteria for half-linear second order differential equations Creator: Pátíková, Zuzana Format: bez média and svazek Type: model:article and TEXT Subject: half-linear differential equation, Hartman-Wintner criterion, Riccati equation, and principal solution Language: English Description: We establish Hartman-Wintner type criteria for the half-linear second order differential equation r(t)Φ(x ′ ))′ + c(t)Φ(x) = 0, Φ(x) = |x| p−2 x, p > 1, where this equation is viewed as a perturbation of another equation of the same form.
