Construction of self dual codes from graphs
Fellah, Nazahet; Guenda, Kenza; Özbudak, Ferruh; Seneviratne, Padmapani (2022-07-01)
In this work we define and study binary codes C-q,C-k and (C-q,C-k) over bar obtained from neighbor- hood designs of Paley-type bipartite graphs P(q, k) and their complements, respectively for q an odd prime. We prove that for some values of q and k the codes C-q,C-k are self-dual and the codes (C-q,C-k) over bar are self-orthogonal. Most of these codes tend to be with optimal or near optimal parameters. Next, we extend the codes C(q,k )to get doubly even self dual codes and find that most of these codes ar...

Proof of the basic theorem on concept lattices in Isabelle/HOL
Sertkaya, Barış; Oğuztüzün, Mehmet Halit S.; Tiefenbach, Andreas; Department of Computer Engineering (2003)
Formel Concept Analysis is an emerging field of applied mathematics based on a lattice-theoretic formalization of the notions of concept and conceptual hierarchy. It thereby facilitates mathematical thinking for conceptual data analysis and knowledge processing. Isabelle, on the other hand, is a generic interactive theory development environment for implementing logical formalisms. It has been instantiated to support reasoning in several object-logics. Specialization of Isabelle for Higher Order Logic is ca...
Proof of the basic theorem on concept lattices in Isabelle/HOL
Sertkaya, B; Oğuztüzün, Mehmet Halit S. (2004-01-01)
This paper presents a machine-checked proof of the Basic Theorem on Concept Lattices, which appears in the book "Formal Concept Analysis" by Canter and Wille, in the Isabelle/HOL Proof Assistant. As a by-product, the underlying lattice theory by Kammueller has been extended.
