NOTES ON EXPLICIT AND INVERSION FORMULAS FOR THE CHEBYSHEV POLYNOMIALS OF THE FIRST TWO KINDS

摘要

In the paper, starting from the Rodrigues formulas for the Chebyshev polynomials of the first and second kinds, by virtue of the Faa di Bruno formula, with the help of two identities for the Bell polynomials of the second kind, and making use of a new inversion theorem for combinatorial coefficients, the authors derive two nice explicit formulas and their corresponding inversion formulas for the Chebyshev polynomials of the first and second kinds.
