Operational vs. Umbral Methods and Borel Transform
Giuseppe Dattoli, Silvia Licciardi
Differintegral methods, currently exploited in calculus, provide a fairly unexhausted source of tools to be applied to a wide class of problems involving the theory of special func…
Repeated derivatives of tanh, sech, ... and associated polynomials
Giuseppe Dattoli, Silvia Licciardi, Rosa Maria Pidatella +1
Elementary problems like the evaluation of repeated derivatives of ordinary transcendent functions can usefully be treated by the use of special polynomials and of a formalism borr…
Dual Numbers and Operational Umbral Methods
Nicolas Behr, Giuseppe Dattoli, Ambra Lattanzi +1
Dual numbers and their higher order version are important tools for numerical computations, and in particular for finite difference calculus. Based upon the relevant algebraic rule…
