A non-existence result for periodic solutions of the relativistic pendulum with friction Torres, Pedro J. Relativistic pendulum Periodic solution Linear friction It is proved that if the damped periodically forced Newtonian pendulum does not have periodic solutions, the same happens for the relativistic version of the problem for high values of the parameter c representing the speed of light in the vacuum. 2023-06-14T06:34:53Z 2023-06-14T06:34:53Z 2023-10 journal article P.J.
