Abstract (EN):
This paper is concerned with the Shohat-Favard, Chebyshev and Modified Chebyshev methods for d-orthogonal polynomial sequences (d is an element of N). Shohat-Favard's method is presented from the concept of dual sequence of a sequence of polynomials. We deduce the recurrence relations for the Chebyshev and the Modified Chebyshev methods for every d is an element of N. The three methods are implemented in the Mathematica programming language. We show several formal and numerical tests realized with the software developed.
