Une rencontre mathématique By Hayden

Suppose that you are given some number of objects that have a set order but have been randomly shuffled. Without any prior information, you are given the task of putting the objects back into their correct order. How many ways could you arrange the objects? How well do you expect to do? Would this change if there were more objects? Recently I was faced with these very questions and, in the proc...

On Codes over $\mathbb{F}_{q}+v\mathbb{F}_{q}+v^{2}\mathbb{F}_{q}$

In this paper we investigate linear codes with complementary dual (LCD) codes and formally self-dual codes over the ring $R=\F_{q}+v\F_{q}+v^{2}\F_{q}$, where $v^{3}=v$, for $q$ odd. We give conditions on the existence of LCD codes and present construction of formally self-dual codes over $R$. Further, we give bounds on the minimum distance of LCD codes over $\F_q$ and extend these to codes ove...
