Log-Concave Sequences in Coding Theory
Minjia Shi, Xuan Wang, Junmin An +1
We introduce the notion of logarithmically concave (or log-concave) sequences in Coding Theory. A sequence of real numbers is called log-concave if $a_i^2 \g…

Expanding self-orthogonal codes over a ring to self-dual codes and unimodular lattices
Minjia Shi, Sihui Tao, Jihoon Hong +1
Self-dual codes have been studied actively because they are connected with mathematical structures including block designs and lattices and have practical applications in quantum e…
