The best linear methods and values of widths for some classes of analytic functions in the Bergman weight space

K-FUNCTIONALS AND EXACT VALUES OF n-WIDTHS IN THE BERGMAN SPACE

“…We obtain equality (9) by comparing the upper bound (15) with the lower bound (17). The theorem is proved.…”

“…We note that, in the Bergman space, values of widths of some classes of analytic functions in a disk were calculated, for example, in [13][14][15][16][17][18][19].…”
