A transform involving Chebyshev polynomials and its inversion formula

We define a functional analytic transform involving the Chebyshev polynomials Tn (x), with an inversion formula in which the Möbius function μ (n) appears. If s ∈ C with Re (s) > 1, then given a bounded function from [- 1, 1] into C, or from C into itself, the following inversion formula holds:g...

Resumo:We define a functional analytic transform involving the Chebyshev polynomials Tn (x), with an inversion formula in which the Möbius function μ (n) appears. If s ∈ C with Re (s) > 1, then given a bounded function from [- 1, 1] into C, or from C into itself, the following inversion formula holds:g (x) = underover(∑, n = 1, ∞) frac(1, ns) f (Tn (x)) if and only iff (x) = underover(∑, n = 1, ∞) frac(μ (n), ns) g (Tn (x)) .
