On the best approximation by “angles” in the mean on the plane $\mathbb{R}^2$ with the Chebyshev-Hermite weight.
Exact inequalities of Jackson type connected with the best approximation by ''angles''  of algebraic polynomials are obtained on the classes of differentiable functions of two variables in the metric of space $L_{2,\rho}(\mathbb{R}^2)$ at the Chebyshe...
