Abstract
In this paper, we consider an elliptic system arising from the study of the Maxwell-Chern-Simons model, which involves two distinct parameters: the Chern-Simons mass scale mu and the inverse Chern-Simons parameter lambda. We first establish the equivalence between stable solutions and topological solutions with respect to the two distinct parameters in the Chern-Simon type regime. To address stability of our elliptic system, we study a reduced functional involving the Laplacian, and biharmonic terms appear in the corresponding linearized operator of the second Fr & eacute;chet derivative. So, meticulous analysis is required to handle the biharmonic terms as well as the disparate scales of the two parameters. Furthermore, we show the uniqueness of stable solutions in the Chern-Simon type regime. (c) 2025 Elsevier Inc.
