Trigonometric polynomials of least deviation from zero in measure and related problems [PDF]

Journal of Approximation Theory, 2010
We give a solution of the problem on trigonometric polynomials fn with the given leading harmonic ycosnt that deviate the least from zero in measure, more precisely, with respect to the functional μ(fn)=mes{t∈[0,2π]:|fn(t)|≥1}.

On multivariate polynomials of least deviation from zero on the unit cube [PDF]

Journal of Approximation Theory, 1978
In the family of all r-variable real polynomials with total degree not exceeding μ and with maximum norm on the unit-cube not exceeding 1, any of the leading coefficients is maximum for a special product of one-variable Chebyshev polynomials of the first
