Vougalter, Vitali; Volpert, Vitaly Solvability conditions for some systems with non Fredholm operators. (English) Zbl 1399.35152 Int. Electron. J. Pure Appl. Math. 2, No. 3, 183-187 (2010). Summary: We derive solvability conditions in \(H^2\) (\(\mathbb R^3; \mathbb R^2\)) for certain systems of nonhomogeneous elliptic partial differential equations involving Schrödinger type operators without Fredholm property using the technique developed in preceding works [V.
