Boundary unique continuation for a class of elliptic equations
S. Berhanu · American Journal of Mathematics · 2021
We establish results on unique continuation at the boundary for the solutions of real analytic elliptic partial differential equations of the form $Lu=\Delta u+a(x,y)\partial_{x}u+b(x,y)\partial_{y}u+c(x,y)u=0$ in two dimensions.
