Chebyshev Polynomials on Compact Sets [PDF]
The author proves that if a compact set \(K\) in the complex plane contains a smooth Jordan curve on its outer boundary, then the minimal norm of the \(n\)-th Chebyshev polynomial \(T_n\) on \(K\) satisfies \(\|T_n\|_K\geq (1+\beta)\mathrm{cap}(K)^n\), for some \(\beta>0\) where \(\mathrm{cap}(K)\) is the logarithmic capacity of \(K\).

Some Identities Involving Chebyshev Polynomials [PDF]
The main purpose of this paper is using the combinatorial method and algebraic manipulations to study some sums of powers of Chebyshev polynomials and give several interesting identities. As some applications of these results, we obtained several divisibility properties involving Chebyshev polynomials.

Chebyshev polynomials are not always optimal [PDF]
The problem is that of finding among all polynomials of degree at most n and normalized to be 1 at c the one with minimal uniform norm on Epsilon. Here, Epsilon is a given ellipse with both foci on the real axis and c is a given real point not contained ...

Prediction of compliant wall drag reduction, part 1 [PDF]
Computer codes developed to test Bushnell's compliant wall drag reduction model are discussed. One code computes the evolution of mean velocity profiles during the period between bursts as forced by an imposed large-scale pressure pulse due to earlier ...
