An algebraic approach to laying a ghost to rest
M. C. Nucci, P. G. L. Leach
In the recent literature there has been a resurgence of interest in the fourth-order field-theoretic model of Pais-Uhlenbeck \cite {Pais-Uhlenbeck 50 a}, which has not had a good r…

On the inverse problem of calculus of variations
M. C. Nucci, A. M. Arthurs
We show that given an ordinary differential equation of order four, it may be possible to determine a Lagrangian if the third derivative is absent (or eliminated) from the equation…

Jacobi's last multiplier and the complete symmetry group of the Euler-Poinsot system
M. C. Nucci, P. G. L. Leach
The symmetry approach to the determination of Jacobi's last multiplier is inverted to provide a source of additional symmetries for the Euler-Poinsot system. These additional symme…
