Congruence preserving functions in the residue class rings of polynomials over finite fields
Xiumei Li, Min Sha
In this paper, as an analogue of the integer case, we define congruence preserving functions over the residue class rings of polynomials over finite fields. We establish a counting…

Weight hierarchies of a family of linear codes associated with degenerate quadratic forms
Fei Li, Xiumei Li
We restrict a degenerate quadratic form over a finite field of odd characteristic to subspaces. Thus, a quotient space related to is introduced. Then we get a non-degenerat…
