Heteroclinic solutions for some classes of prescribed mean curvature equations in whole R2

The purpose of this paper consists in using variational methods to establish the existence of heteroclinic solutions for some classes of prescribed mean curvature equations of the type - d i v ∇ u 1 + | ∇ u | 2 + A ( ϵ x , y ) V ′ ( u ) = 0 in R 2 , where ϵ > 0 and V is a double-well potential with minima at t = α and t = β with α < β . Here, we consider some class of functions A ( x , y ) that are oscillatory in the variable y and satisfy different geometric conditions such as periodicity in all variables or asymptotically periodic at infinity.
