Abstract
The functional integrals corresponding to Sturm-Liouville equation and linear as well as nonlinear Dirac system are derived. The invariance of the resulting functional integrals are studied under a one-parameter group of transformations (Lie group). Finally, conservation laws are obtained through the applications of the invariant variational principle technique and classes of solutions are given in some cases.
