Approximation on compact sets of functions and all derivatives
Sotiris Armeniakos, Giorgos Kotsovolis, Vassili Nestoridis
In Mergelyan type approximation we uniformly approximate functions on compact sets K by polynomials or rational functions or holomorphic functions on varying open sets containing K…

Partially Smooth Universal Taylor Series on products of simply connected domains
Giorgos Kotsovolis
Using a recent Mergelyan type theorem, we show the existence of universal Taylor series on products of planar simply connected domains Oi that extend continuously on the product of…

Universal Taylor Series on products of planar domains
K. Kioulafa, G. Kotsovolis, V. Nestoridis
Using a recent Mergelyan type theorem for products of planar compact sets we establish generic existence of Universal Taylor Series on products of planar simply connected domains O…
