Hermitian Duality and Syndrome Structure of CSS-Type Codes over the ring $Z_{q} [i]$

Akanksha Tiwari, Ritumoni Sarma

We study the algebraic structure of principal ideal codes and CSS-type stabilizer constructions over the ring $R_{q} = Z_{q} [i],$ where every prime divisor of $q$ is congruent t…

Linear Codes over $F_{q} + u F_{q}$ associated with Simplicial Complexes, Their Gray Images, and Subfield Codes

Ankit Yadav, Akanksha Tiwari, Ritumoni Sarma

In recent years, simplicial complexes have gained considerable attention as a useful tool for constructing distance-optimal codes over finite fields. In this article, we construct…

Skew Polycyclic Codes over $\frac{F _{p^{m}} [ u ]}{⟨ u ^{t} ⟩}$

Akanksha Tiwari, Ritumoni Sarma

Let $R^{t}$ denote the finite chain ring $\frac{F _{p^{m}} [ u ]}{⟨ u ^{t} ⟩},$ where $p$ is a prime and $t$ is a positive integer. In this article, for a prime $p$ and a…
