Map

Definition

In the context of decoding techniques for AG codes, a map is a systematic way of associating elements from one set with elements from another, typically transforming or encoding information. This process is essential for converting received messages back into their original forms, making it possible to detect and correct errors introduced during transmission. A map serves as a fundamental tool that links the algebraic structure of the codes to their practical implementation in decoding.
