Singular Lagrangians
Opis:: We exhibit an elementary presentation of matrix and Noether techniques to construct infinitesimal point symmetries of Lagrangians. Besides, we employ the Lanczos approach to Noether’s theorem to obtain the first integral associated with each symmetry. We show applications to several singular Lagrangians of interest in classical mechanics.

Singular Lagrangians
Opis:: For several Lagrangians we show that their local symmetries can be obtained from the associated Euler-Lagrange equations, and we exhibit the explicit presence of the genuine constraints into gauge identities. We also employ the Lanczos approach to Noether’s theorem to give connections between the genuine constraints and their time derivatives. Besides, it is evident that the Hamiltonian secondary and tertiary constraints have relationship with the genuine constraints.
