The inverse problem for Lagrangian systems with certain non-conservative forces
T. Mestdag, W. Sarlet, M. Crampin
We discuss two generalizations of the inverse problem of the calculus of variations, one in which a given mechanical system can be brought into the form of Lagrangian equations wit…

On the generalized Helmholtz conditions for Lagrangian systems with dissipative forces
M. Crampin, T. Mestdag, W. Sarlet
In two recent papers necessary and sufficient conditions for a given system of second-order ordinary differential equations to be of Lagrangian form with additional dissipative for…
