Abstract: We discuss approximation of extremal functions by polynomials in the weighted Bergman spaces $$A^p_\alpha $$Aαp where $$-1< \alpha < \min (0,p-2)$$-1 read more here.

Abstract: Abstract The ultrametrically injective hull TX of an ultrametric space (X, d) is investigated by viewing it as the space of ultra-extremal functions over X. It turns out that the ultra-extremal functions are also ultra-Kaťetov… read more here.
