Abstract: In this paper we investigate properties of solutions of first and second order elliptic equations that degenerate along a simple closed curve in $ \mathbb{R}^2$. These equations are generated by a $ \mathbb{C}$-valued vector field $ L$. To the vector field $ L$, we associate the second order operator $ \mathbb{P}=\mathrm{Re}\left[L\overline{L}+p L \right]$, where $ p$ is a $ \mathbb{C}$-valued function. We establish a one-to-one correspondence between the solutions of the equation $ \mathbb{P}u=0$ and those of an associated first order equation of type $ Lw=Aw+B\overline{w}$.
