In this article we compute equations satisfied by the canonical theta null point of the canonical lift of an ordinary abelian variety in characteristic 2. In contrast to the equations studied by J.-F. Mestre et al. ours are valid over an arbitrary 2-adic ring which possibly is of positive characteristic.
متن کاملov 2 00 6 Energy and time as conjugate dynamical variables
The energy and time variables of the elementary classical dynami-cal systems are described geometrically, as canonically conjugate coordinates of an extended phase-space. It is shown that the Galilei action of the inertial equivalence group on this space is canonical, but not Hamiltonian equivari-ant. Although it has no effect at classical level, the lack of equivariance makes the Galilei actio...

Under an appropriate change of the perturbation variable LifshitzKhalatnikov propagation equations for the scalar perturbation reduce to d’Alembert equation. The change of variables is based on the Darboux transform.
