Abstract: In this paper we investigate properties of solutions of first and second order elliptic equations that degenerate along a simple closed curve in . These equations are generated by a -valued vector field . To the vector field , we associate the second order operator , where is a -valued function. We establish a one-to-one correspondence between the solutions of the equation and those of an associated first order equation of type .
