Resumen de Doubly extended codes for general metrics
In this work, doubly extended codes are generalized to any metric and to any initial code to be extended. In particular, doubly extended maximum sum-rank distance (MSRD) codes are obtained from several families of known MSRD codes. These resultsgeneralize classical doubly extended Reed-Solomon codes for the Hamming metric and the recent doubly extended linearized Reed-Solomon codes for the sum-rank metric.
