Mukherjee, R. N.; Som, T. A note on an application of a fixed point theorem in approximation theory. (English) Zbl 0606.41048 Indian J. Pure Appl. Math. 16, 243-244 (1985). We extend a theorem of S. P. Singh [J. Approximation Theory 25, 89- 90 (1979)] by relaxing further the condition of star-shapedness on the set of best C-approximations to a given point.
