| Abstract: | A lower estimate of the least deviations is obtained and polynomials of the best uniform approximation are found for some functions given on compact sets of the complex plane containing complete preimages Q ?1(v j ) of several points v j ?? ? for some polynomial Q(z) of complex variable. |
