摘要
We consider the generalized Neumann problem for a 2lth-order elliptic equation with constant real higher-order coefficients in an infinite domain containing the exterior of some circle and bounded by a sufficiently smooth contour. It consists in specifying of the (kj − 1)th-order normal derivatives where 1 ≤ k 1 <.. < kl ≤ 2l; for kj = j it turns into the Dirichlet problem, and for kj = j + 1 into the Neumann problem. Under certain assumptions about the coefficients of the equation at infinity, a necessary and sufficient condition for the Fredholm property of this problem is obtained and a formula for its index in Hölder spaces is given. © 2024, Springer Nature Switzerland AG.
