Present research interests:

The current research around the sequences of integers inspires and provide numerous specializations and generalizations. From 2013 I have studied of sequences of special numbers, investigating some of their algebraic properties, their generating functions and generating matrices. Sequences of quaternions, octonions, sedenions and polynomials will also be the focus of my research. The relationship of these sequences with several types of matrices (for instance, Hessenberg, circulant, tridiagonal, etc.), whose entries are the elements of such sequences, and respective norms will be studied, providing some results involving them and study the invertibility of these type matrices. Also I am working on semigroups and in area of Mathematical Education.
