Localization Results for Impulsive Second Order Coupled Systems on the Half-Line and Application to Logging Timber by Helicopter

  • Feliz Minhós
  • Robert de SousaEmail author


This work considers two types of a second order impulsive coupled system of differential equations with generalized jump conditions in half-line. For both problems it will be presented two localization results with different monotonicity assumptions on the nonlinearities and on the impulsive conditions.

The arguments apply lower and upper solutions method combined with Nagumo type condition and truncature techniques.

Last section contains an applications of one of this impulsive problems to logging timber by helicopter.
