Re: [math-fun] 0.9999... = 1 and all that

P.S. It may be that the sum-of-coordinates function can't be extended to Hilbert space from the absolutely convergent series, in such a way that it's continuous. Recall that I recently asked about the set of points in Hilbert space whose coordinates sum to 0, and it turns out to be a dense subset of Hilbert space. --Dan Daniel Asimov Visiting Scholar Department of Mathematics University of California Berkeley, California
