We generalize the universal power series of Seleznev to several variables and we allow coefficients depend on parameters. Then, approximable functions may same The approximation holds products $$K = \displaystyle \prod \nolimits _{i 1}^d K_i$$ , where $$K_i \subseteq \mathbb {C}$$ are compact sets $$\mathbb {C} {\setminus } connected, $$i 1, \ldots d$$ $$0 \notin K$$ . On such K partial sums ap...
