I. V. Belyakov Moscow State Institute of Electronics and Mathematics
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 $A_\alpha$.
Keywords:
Chebyshev and trigonometric polynomials, minimal deviation property, symmetric algebras, complex Lie algebra.
