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…
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…
Permutation-generated maps between Dyck paths
Kevin Limanta, Hopein Christofen Tang, Yozef Tjandra
In 2003, Deutsch and Elizalde defined a family of bijective maps between the set of Dyck paths to itself which is induced by some particular permutations. In this paper, we extend…
