Fethi Bouzeffour

Fethi Bouzeffour is a mathematics professor at King Saud University specializing in advanced mathematical analysis with contributions to areas such as fractional calculus, special functions, and harmonic analysis. His research spans fractional integral and differential operators (including generalized and Dunkl-type fractional operators), orthogonal polynomials and q-calculus, and integral transforms like the generalized Fourier and Hartley transforms. He has also worked on oscillator algebras in mathematical physics, including q-oscillator and C_λ-extended oscillator algebras connected with d-orthogonal polynomials, and explored special functions associated with root systems . These interests tie together abstract analysis, algebraic structures, and applications in theoretical physics.
