| Abstract: | For a wide class of symmetric trigonometric polynomials, the minimal deviation property is established. As a corollary, the extremal property is proved for the components of the Chebyshev polynomial mappings corresponding to symmetric algebras A α. |
| Keywords: | Chebyshev and trigonometric polynomials minimal deviation property symmetric algebras complex Lie algebra |
