Convergence of Taylor series in several variables

  1. Aug 23, 2010 #1
    where do a multiple Taylor series converge ??

    i mean if given a function [tex] f(x,y) [/tex] can i expand this f into a double Taylor series that will converge on a rectangle ? for example , if one can ensure that it converges for |x| <1 and |y| <1

    It depends very much on what f is.
