[edit] Divergent_series

Thanks for the fix on the stability condition. I'm going to try to make sure the situation is more overt by casting the conditions in both forms. –Dan Hoey 20:11, 15 April 2007 (UTC)

I'm a little less sure about changing the definition of stability. The two aren't equivalent without linearity. Are you sure the usual definition of stability assumes that A({c+s_n}) = c+A({s_n})? –Dan Hoey 22:14, 15 April 2007 (UTC)

That's what the discussion at Talk:1 − 2 + 3 − 4 + · · · led me to believe. Without it, the argument discussed there cannot be done without regularity. But as I said, someone should look it up. I did try to change the sequence definition to match your series definition. --Ørjan 23:01, 15 April 2007 (UTC)
