Noether symmetries and isometries of the minimal surface Lagrangian   under constant volume in a Riemannian space
  We prove a theorem concerning the Noether symmetries for the area minimizing Lagrangian under the constraint of a constant volume in an n-dimensional Riemannian space. We illustrate the application of the theorem by a number of examples.
