Abstract :
We study the approximation of multivalued functions in the Fell topology by means of single valued continuous functions or minimal upper semicontinuous compact-valued maps. We give a partial answer to Question 5.5 in [R.A. McCoy, Comparison of hyperspace and function space topologies, in: G. Di Maio, L. Holá, (Eds.), Recent Progress in Function Spaces, in: Quad. Mat., vol. 3, Aracne Editrice, Caserta, 1998, pp. 241–251] and to Question 7 in [R.A. McCoy, Fell topology and uniform topology on compacta on spaces of multifunctions, Rostock. Math. Kolloq. 51 (1997) 127–136].
