TY - JOUR AU - Cui, Yanyan AU - Wang, Chaojun PY - 2024 TI - The inhomogeneous complex partial differential equations for bi-polyanalytic functions JO - AIMS Mathematics SP - 16526 EP - 16543 VL - 9 IS - 6 AB - In this paper, we study a Riemann-Hilbert problem related to inhomogeneous complex partial differential operators of higher order on the unit disk. Applying the Cauchy-Pompeiu formula, we find out the solvable conditions and obtain the representation of the solutions. Then, we investigate the boundary value problems for bi-polyanalytic functions with the Dirichlet and Riemann-Hilbert boundary conditions, obtain the specific solution and the solvable conditions, and extend the conclusion to the corresponding higher-order problems. Therefore, we obtain the solution to the half-Neumann problem of higher order for bi-polyanalytic functions. UR - https://doi.org/10.3934/math.2024801 DO - 10.3934/math.2024801
