Abstract
We study the equilibrium states for an energy functional with a parametric force eld on a region
of a surface. Consideration of free equilibrium states is based on Lyusternik - Schnirelman's and
Skrypnik's variational methods. Consideration of equilibrium states under a constraint of geometrical
character is based on an analog of Skrypnik's method, described in [P. Vyridis, Bifurcation in a
Variational Problem on a Surface with a Constraint, Int. J. Nonlinear Anal. Appl. 2 (1) (2011),
1-10]. In local coordinates, equilibrium points satisfy an elliptic boundary value problem.
