Periodic representations for cubic irrationalities
Marco Abrate, Stefano Barbero, Umberto Cerruti +1
In this paper we present some results related to the problem of finding periodic representations for algebraic numbers. In particular, we analyze the problem for cubic irrationalit…
Accelerations of generalized Fibonacci sequences
Marco Abrate, Stefano Barbero, Umberto Cerruti +1
In this paper we study how to accelerate the convergence of the ratios (x_n) of generalized Fibonacci sequences. In particular, we provide recurrent formulas in order to generate s…
Fixed Sequences for a Generalization of the Binomial Interpolated Operator and for some Other Operators
Marco Abrate, Stefano Barbero, Umberto Cerruti +1
This paper is devoted to the study of eigen-sequences for some important operators acting on sequences. Using functional equations involving generating functions, we completely sol…
