Structural Properties of Word Representable Graphs
Somnath Bera,Kalpana Mahalingam +1 more
TL;DR: All Parikh word representable graphs over the binary alphabet in terms of chordal bipartite graphs are characterized and it is shown that G(w), for any word w over binary alphabet, is a complete bipartsite graph.

Some Algebraic Aspects of Parikh q-Matrices
Somnath Bera,Kalpana Mahalingam +1 more
TL;DR: It has been shown that the notion of alternating Parikh q-matrices can be characterized using the q-counting polynomials and it is shown that a Minor of a Parikhq-matrix is a polynomial in q with non-negative coefficients.

Properties of Parikh Matrices of Binary Words Obtained by an Extension of a Restricted Shuffle Operator
TL;DR: An extension of the restricted shuffle operator on binary words considered by Atanasiu and Teh (2016) is introduced and properties on Parikh matrix equivalence of words over a binary alphabet and a weakratio property of words are derived.
Journal Article
Involution solid and join codes
TL;DR: This paper studies a generalization of the classical notions of solid codes and comma-free codes: involution solid codes (θ-solid) and involution join codes ( θ-join), motivated by DNA strand design.
