Abstract
For a linear code, deep holes are defined to be vectors that are further away from codewords than all other vectors. The problem of deciding whether a received word is a deep hole for generalized Reed-Solomon codes is proved to be co-NP-complete [9][5]. For the extended Reed-Solomon codes \(RS_q(\mathbb{F}_q,k)\), a conjecture was made to classify deep holes in [5]. Since then a lot of effort has been made to prove the conjecture, or its various forms. In this paper, we classify deep holes completely for generalized Reed-Solomon codes RS p (D,k), where p is a prime, \(|D| > k \geqslant \frac{p-1}{2}\). Our techniques are built on the idea of deep hole trees, and several results concerning the Erdös-Heilbronn conjecture.
