On the compatibility of non-holonomic systems and certain related variational systems
Christofer Cronstrom
I consider the equations of motion which follow from d'Alembert's principle for a general mechanical system in a space of N dimensions, constrained by a non-holonomic constraint wh…
On non-holonomic systems and variational principles
Christofer Cronstrom, Tommi Raita
We consider the compatibility of the equations of motion which follow from d'Alembert's principle in the case of a general autonomous non-holonomic mechanical system in N dimension…
On the existence of Hamiltonians for non-holonomic systems
Christofer Cronstrom, Tommi Raita
We consider the question of existence of Hamiltonians for autonomous non-holonomic mechanical systems in this paper. The approach is elementary in the sense that the existence of a…
On the uniqueness of solutions to gauge covariant Poisson equations with compact Lie algebras
Christofer Cronstrom
It is shown, under rather general smoothness conditions on the gauge potential, which takes values in an arbitrary semi-simple compact Lie algebra , that if a (-v…
Canonical structure and boundary conditions in Yang-Mills theory
Christofer Cronstrom
The canonical structure of pure Yang-Mills theory is analysed in the case when Gauss' law is satisfied identically by construction. It is shown that the theory has a canonical stru…
New Magnetically Ordered State in the Electron Plasma of Metals
Christofer Cronstrom, Milan Noga
Within the simplest model of metals, namely a gas of electrons with Coulomb interactions, in the presence of a uniform background of positive charge to enforce electric neutrality…
