Sažetak

We analyze the equation of motion for a particle in the double-well potential. We find the symmetries through Lie's method of group analysis. In the corresponding quantum mechanical case, the method of spectrum-generating su(1,1) algebra is used to find energy levels as solutions of the Schrödinger equation with double-well potential, without solving the equation explicitly. Finally, we discuss the symmetry version of the double-well potential with the vector-field formalism.
