报告内容🤾🏽♂️: Goppa codes over $F_{q^m}$ are a well-known subclass of algebraic error-correcting codes. If m = 1, then they are viewed as generalized Reed-Solomon codes. In this paper, we give a necessary and sufficient condition that the dual code of a Goppa code is also a Goppa code, and based on the condition, we obtain the dimension of the hulls of Goppa codes, and show that the hull of a Goppa code is still a Goppa code. As an application, we characterize the LCD Goppa codes and self-dual Goppa codes under the above condition.Some numerical examples are also presented to illustrate our main results. Moreover, we also apply our result to entanglement-assisted quantum error correcting codes (EAQECCs) and obtain two new families of MDS EAQECCs with arbitrary parameters. |
