In the present paper, we isolate a specific universal Taylor series by modifying the proof in . Thus we determine all Taylor coefficients of a specific universal Taylor series on the disc or on a polygonal domain. Furthermore in non simply connected domains, when universal Taylor series exist, we can construct a sequence of specific rational functions converging to a universal function, provided the boundary is good enough. The solution uses an infinite denumerable procedure and a finite number of steps is not sufficient. However we solve a Runge's type problem in a finite number of steps.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||Heldermann Verlag||Copyright (published version):||Heldermann Verlag 2012||Keywords:||Universal series;Taylor series;Runge theorem||Language:||en||Status of Item:||Not peer reviewed|
