New optimal linear codes over $\ZZ_4$
Hopein Christofen Tang, Djoko Suprijanto
In this work, we present novel approaches for constructing linear codes over $\ZZ_4$ from the known ones. We succeeded in obtaining new linear codes, many of which are optimal. In…
A multiset approach to MacWilliams identities
Hopein Christofen Tang
We interpret the symmetrized weight enumerator of linear codes over finite commutative Frobenius rings as a summation over multisets and thereby provide a new proof of the MacWilli…
Harmonic Tutte polynomials of matroids II
Thomas Britz, Himadri Shekhar Chakraborty, Reina Ishikawa +2
In this work, we introduce the harmonic generalization of the -tuple weight enumerators of codes over finite Frobenius rings. A harmonic version of the MacWilliams-type identity…
A general family of Plotkin-optimal two-weight codes over
Hopein Christofen Tang, Djoko Suprijanto
We obtain all possible parameters of Plotkin-optimal two-Lee weight projective codes over together with their weight distributions. We show the existence of codes w…
Bounds on the closeness centrality of a graph
Thomas Britz, Xin Hu, Abdellah Islam +1
We present new values and bounds on the (normalised) closeness centrality of connected graphs and on its product with the mean dist…
Quantum codes constructed from cyclic codes over the ring
Djoko Suprijanto, Hopein Christofen Tang
In this article, we investigate properties of cyclic codes over a finite non-chain ring where …
