An interpolatory estimate for copositive polynomial approximations of continuous functions
UDC 517.9 Under the condition that a function $f$, which is continuous on $[-1,1],$ changes its sign at $s$ points $y_i,$ $-1 < y_{s} < y_{s-1} < \dots < y_1 < 1,$ then for each $n \in \mathbb{N}$ greater than some constant $\mathbb{N}$ dependin...
