Symmetry Group of Tzitzeica Surfaces PDE
Udriste Constantin, Bila Nicoleta
Using the symmetry group theory of second order PDEs, one finds the symmetry group associated to Tzitzeica surfaces partial differential equation. One studies the inverse problem a…

Symmetry groups and Lagrangians associated to Tzitzeica surfaces
Bila Nicoleta
One applies the symmetry group theory for study the partial differential equations of Tzitzeica surfaces theory. One finds infinitesimal symmetries, Lagrangians and a new solution…
