Pais-Uhlenbeck Oscillator with a Benign Friction Force
Matej Pavšič
It is shown that the Pais-Uhlenbeck oscillator with damping, considered by Nesterenko, is a special case of a more general oscillator that has not only a first order, but also a th…
Stable Self-Interacting Pais-Uhlenbeck Oscillator
Matej Pavšič
It is shown that the interacting Pais-Uhlenbeck oscillator necessarily leads to a description with a Hamiltonian that contains positive and negative energies associated with two os…
Wheeler-DeWitt Equation in Five Dimensions and Modified QED
Matej Pavšič
We consider the ADM splitting of the Einstein-Hilbert action in five dimensions in the presence of matter that can be either a "point particle", or a set of scalar fields. The Hami…
The Classical and Quantum Theory of Relativistic p-Branes without Constraints
Matej Pavsic
It is shown that a relativistic (i.e. a Poincar{\' e} invariant) theory of extended objects (called p-branes) is not necessarily invariant under reparametrizations of corresponding…
