الملخص الإنجليزي

The higher—order regular Lagrangian is reduced to first-order singular Lagrangian.

Dirac’s method of discrete regular systems with higher—order Lagrangian, are stud¬ied as singular systems with first-order Lagrangian, and the equations of motion are obtained.

It is shown that the Hamilton—Jacobi approach leads to the same equa¬tions of motion as obtained by Dirac’s method.

The second—order and third—order Lagrangian are studied as an examples.

The Hamilton—Jacobi formulation for first—order constrained systems has been discussed.

In such formalism the equa¬tions of motion are written as total differential equations in many variables.

We generalize the Hamilton—Jacobi formulation for singular systems with second—order Lagrangians and apply this new formulation to Podolsky electrodynamics, compar¬ing the results with the results obtained through Dirac’s method.

The equations of motion for the associated Lagrangian to a nonholonomic Lagrangian of second—order are computed in both methods Dirac and Hamilton—Jacobi.

Besides, the canonical path integral quantization was obtained to quantize singular systems.

All the results obtained using Hamilton—Jacobi method, are in exact agreement with those results obtained using Dirac’s method.
