Direct theorems of trigonometric approximation for variable exponent Lebesgue spaces
(Union Matematica Argentina, 2019)Jackson type direct theorems are considered in variable exponent Lebesgue spaces L-p(x) with exponent p(x) satisfying 1 <= ess inf(x is an element of[0,2 pi]) p(x), ess sup(x is an element of[0,2 pi]) p(x) < infinity, and ... -
