Integrability and the variational formulation of non-conservative mechanical systems
David Delphenich
It is shown that one can obtain canonically-defined dynamical equations for non-conservative mechanical systems by starting with a first variation functional, instead of an action…

Projective geometry and special relativity
David Delphenich
Some concepts of real and complex projective geometry are applied to the fundamental physical notions that relate to Minkowski space and the Lorentz group. In particular, it is sho…

Symmetries and pre-metric electromagnetism
David Delphenich
The equations of pre-metric electromagnetism are formulated as an exterior differential system on the bundle of exterior differential 2-forms over the spacetime manifold. The gener…
