| Abstract: | The authors establish the condition for the existence of the Chebyshev approximation by the sum of the polynomial and logarithmic expression with the least absolute error and Hermite interpolation at the end points of the interval. The method is proposed for determining the parameters of such Chebyshev approximation. |
