Generalized Fibonacci and Lucas cubes arising from powers of paths and cycles
Pietro Codara, Ottavio M. D'Antona
The paper deals with some generalizations of Fibonacci and Lucas sequences, arising from powers of paths and cycles, respectively. In the first part of the work we provide a formul…
Eulerian digraphs and Dyck words, a bijection
Pietro Codara, Ottavio M. D'Antona, Marco Genuzio
The main goal of this work is to establish a bijection between Dyck words and a family of Eulerian digraphs. We do so by providing two algorithms implementing such bijection in bot…
An Analysis of Ruspini Partitions in Gödel Logic
Pietro Codara, Ottavio M. D'Antona, Vincenzo Marra
By a Ruspini partition we mean a finite family of fuzzy sets , , such that for all , where …
Valuations in Gödel Logic, and the Euler Characteristic
Pietro Codara, Ottavio M. D'Antona, Vincenzo Marra
Using the lattice-theoretic version of the Euler characteristic introduced by V. Klee and G.-C. Rota in the Sixties, we define the Euler characteristic of a formula in Gödel logic…
