Global existence of a heavy ball model with a varying nonnegative friction
Published 25 Apr 2018 in math.AP | (1804.09388v1)
Abstract: In this paper, we study a dissipative dynamical system non linear of second order $ \ddot{x}(t)+\lambda(t)\, \dot{x}(t)+\nabla \Phi (x(t))=0,$ with the non-negative friction coefficient $\lambda \in \mathcal{C}([0,+\infty[)$ and the internal constraint $\Phi \in \mathcal{C}2$.
