The uniqueness of the best non-symmetric $L_1$-approximant with a weight by $A_{\alpha ,\beta }$-subspace

The questions of the uniqueness of the best non-symmetric $L_1$-approximant with weight in the finite dimensional subspace and the connection of such tasks with $A_{\alpha ,\beta }$-subspaces were considered in this article. This result generalizes the known result of Kroo on the case of non-symme...
