Equilibria of static systems
Wlodzimierz M. Tulczyjew
A conceptual framework for variational formulations of physical theories is proposed. Such a framework is displayed here just for statics, but it is designed to be subsequently ada…
Regularity of generating families of functions
Wlodzimierz M. Tulczyjew, Pawel Urbanski
We describe the geometric structures involved in the variational formulation of physical theories. In presence of these structures, the constitutive set of a physical system can be…
Liouville structures
W. M. Tulczyjew, P. Urbanski
A 'Liouville structure' is a structure isomorphic to a cotangent vector fibration. A Liouville structure is an essential ingredient of every variational formulation of a physical t…
Density operators and selective measurements
Wlodzimierz M. Tulczyjew
It is widely believed that statistical interpretation of quantum mechanics requires that density operators representing quantum states be normalized. We present a description of se…
Time reflection and the dynamics of particles and antiparticles
Giuseppe Marmo, Wlodzimierz M. Tulczyjew
In this paper we continue our analysis of a formulation of electrodynamics fully covariant under the full Poincaré group. Transformations under the four different components of the…
Space-time orientations and Maxwell's equations
Giuseppe Marmo, Emanuele Parasecoli, Wlodzimierz M. Tulczyjew
An analysis of the concept of orientation used in electrodynamics is presented. At least two different versions are encountered in the literature. Both are clearly identified and c…
