چکیده

In this paper, we study the asymptotics of the discrete Chebyshev polynomials tn(z,N) as the degree grows to infinity. Global asymptotic formulas are obtained as n → ∞, when the ratio of the parameters n/N = c is a constant in the interval (0, 1). Our method is based on a modified version of the Riemann-Hilbert approach first introduced by Deift and Zhou.

Asymptotics of Chebyshev Polynomials, I. Subsets of R

We consider Chebyshev polynomials, Tn(z), for infinite, compact sets e ⊂ R (that is, the monic polynomials minimizing the sup–norm, ‖Tn‖e, on e). We resolve a 45+ year old conjecture of Widom that for finite gap subsets of R, his conjectured asymptotics (which we call Szegő–Widom asymptotics) holds. We also prove the first upper bounds of the form ‖Tn‖e ≤ QC(e) (where C(e) is the logarithmic ca...

Szegő-Widom asymptotics of Chebyshev polynomials on circular arcs

We review the main results of the seminal paper of Widom [2] on asymptotics of or-thogonal and Chebyshev polynomials associated with a set E (i.e., the monic polynomialsof degree at most n that minimize the sup-norm‖Tn‖E), where E is a system of Jordanregions and arcs. Thiran and Detaille [1], considered the Chebyshev polynomials Tn on acircular arc Aα and managed to fin...

A fractional type of the Chebyshev polynomials for approximation of solution of linear fractional differential equations

In this paper we introduce a type of fractional-order polynomials based on the classical Chebyshev polynomials of the second kind (FCSs). Also we construct the operational matrix of fractional derivative of order $ gamma $ in the Caputo for FCSs and show that this matrix with the Tau method are utilized to reduce the solution of some fractional-order differential equations.

A spectral method based on the second kind Chebyshev polynomials for solving a class of fractional optimal control problems

In this paper, we consider the second-kind Chebyshev polynomials (SKCPs) for the numerical solution of the fractional optimal control problems (FOCPs). Firstly, an introduction of the fractional calculus and properties of the shifted SKCPs are given and then operational matrix of fractional integration is introduced. Next, these properties are used together with the Legendre-Gauss quadrature fo...
