On Ritt's decomposition Theorem in the case of finite fields
A classical theorem by Ritt states that all the complete decomposition chains
of a univariate polynomial satisfying a certain tameness condition have the
same length. In this paper we present our conclusions about the generalization
of these theorem in the case of finite coefficient fields when the tameness
condition is dropped.Comment: 13 pages. v2: added comment from reader and additional reference
