Abstract

Diaz and McLaughlin [1], [2] and Dunham [4] have considered the problem of simultaneous approximation of the following case: X=C [a,b], K a non-empty subset of X and F={f1,f2}. Goel, Holland, Nasim and Sahney [5], [6] studied the problem of X a normed linear space, K a subset and F = {f1 f2}.
