Two constants of motion in the generalized damped oscillator

초록

In this paper we consider two types of the generalized damped oscillator. One is governed by a single frictional force which has a position dependent frictional coeffcient and is proportional to the N-th power of the velocity. Another is a quadratically damped harmonic oscillator. For two models, we construct two independent constants of motion. ? 2015 Eun Ji Jang and Won Sang Chung.
