Abstract : The report describes the problem of finding the polynomial which deviates least from the given abstract function, that is, a polynomial for which the best approximation is obtained. This problem is a natural generalization of Chebyshev's problem of approximating real functions by real polynomials, approximating complex functions by complex polynomials, and vector functions with values in a finitedimensional unitary space by vector polynomials.
