In the present paper, we isolate a specific universal Taylor series by modifying the proof in [30]. 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Heldermann Verlag 2012 | Keywords: | Universal series;Taylor series;Runge theorem | Language: | en | Status of Item: | Not peer reviewed |
