摘要：
On different compact sets from R-n, new multidimensional analogs of algebraic polynomials of least deviation from zero (the Chebyshev polynomials) are constructed. A brief review of the analogs constructed earlier is given. Estimates of best approximations obtained by using extremal signatures, lattices, and finite groups are presented.
