- Abstract
We exhibit a simple motivation of the Dfaz-Higuita-Montesinos formula about the physical degrees of freedom count in terms of Lagrangian parameters. For several singular Lagrangians we illustrate the validity of this fotmula to obtain the number of physical degrees of freedom. Besides, we introduce one arbitrary function by each effective gauge parameter to apply the Lanczos version of the Noether theorem, and thus to show the corresponding genuine constraints and their conservation by the time evolution.
