International Journal “Notes on Number Theory and Discrete Mathematics” is delighted to announce to its readership that as of December 2025 the Editorial Board has gained as new members five outstanding scholars in the thematic areas of the Journal. We would like to warmly welcome and thank Prof. Diana Savin, Prof. Can Kızılateş, Prof. Carlos M. da Fonseca, Prof. Emrah Polatlı and Prof. Engin Özkan for accepting our invitations to join our team.
Members of the NNTDM Editorial Board play a vital role in evaluating submissions, promoting the Journal, and guiding its thematic focus and future development. As an all-volunteer, academic-led, and academic-owned non-profit publication, we rely entirely on our Editors to uphold the high standards and strong reputation of NNTDM within the research community.
Prof. Diana Savin works at the Department of Mathematics and Computer Science, Transilvania University of Brașov, Romania. Her research primarily centers on algebraic and computational number theory (fields such as algebraic number fields, Diophantine equations, elliptic curves), associative algebras (notably quaternion and symbol algebras), and combinatorics with an emphasis on special number sequences and generating functions.
Prof. Can Kızılateş works at the Department of Mathematics, Zonguldak Bulent Ecevit University, Türkiye. His research focuses on special number sequences, matrix theory, and their applications within discrete mathematics and algebra. His work often involves generalized Fibonacci-type sequences, special matrices, and related polynomials and generating functions.
Prof. Carlos M. da Fonseca is affiliated with the Kuwait College of Science and Technology, Kuwait. He works works primarily in combinatorial matrix theory and spectral graph theory, with strong emphasis on structured matrices, eigenvalue problems, and discrete mathematics.
Prof. Engin Özkan works at the Department of Mathematics, Marmara University, Türkiye. His research concentrates on number theory, algebra, and applied mathematics — especially on integer sequences and their polynomials (e.g., generalized Fibonacci / Mersenne sequences), recurrence relations, and applications of these sequences in algebraic structures.
Prof. Emrah Polatlı works at the Department of Mathematics, Zonguldak Bülent Ecevit University, Türkiye. He works mainly in linear algebra, combinatorics and number theory, with particular emphasis on matrix theory (e.g., special matrices, their determinants/inverses/norms), integer sequences (like generalized Fibonacci/Lucas sequences), and related structures such as quaternions and hybrid numbers.
The expansion of the NNTDM Editorial Board reflects the consistent rise in submissions we have experienced in recent years. This growth has been particularly notable since the Journal was included in the Emerging Sources Citation Index of Web of Science™ and received its Journal Citation Index rating (JCI 2024 = 0.6, Q3).
We use the opportunity to express our deep appreciation for those scholars who have served on the Editorial Board for many years, and we extend our heartfelt thanks to all of them for their continued dedication and support.
