Source abstract
This editorial introduces the Special Issue of Mathematics “Combinatorics, Riordan Matrices and Umbral Calculus—in Memory of Professor Emanuele Munarini,” which collects ten peer-reviewed papers on theoretical and applied aspects of enumerative combinatorics, combinatorial matrices, and polynomial sequences. The contributions cover a variety of topics and methods, including generating functions, Riordan arrays, recurrence relations, and related combinatorial structures. The Special Issue’s scope and individual contributions are briefly discussed.
