We survey half-linear dynamic equations on time scales. These contain the well-know half-linear differential and half-linear difference equations as special cases, but also other kinds of half-linear equations. Special cases of half-linear equations are the well-studied linear equations of second order. We discuss existence and uniqueness of solutions of corresponding initial value problems and, using a Picone identity, derive a Reid roundabout theorem that gives conditions equivalent to disconjugacy of half-linear dynamic equations, among them solvability of an associated Riccati equation and positive definiteness of an associated functional. We also develop a corresponding Sturmian theory and discuss methods of oscillation theory, which we use to present oscillation as well as nonoscillation criteria for hall-linear dynamic equations.

Článek prezentuje přehled výsledku v teorii pololineárních dynamických rovnic, které sjednocují diferenciální a diferenční rovnice a rovněž jiné typy pololineárních rovnic. Zejména je diskutována otázka existence a jednoznačnosti počátečního problému a oscilační teorie.
