Re: [sage-devel] Re: LazyPowerSeriesRing Replacement
PS: there are probably some things that have to be replaced. For example, LazyPowerSeriesRing has methods `sum_generator` and `product_generator`, which are undocumented but seem to compute the sum/product of a sequence of series where the n-th series (-1 in the product case) has valuation at least n.

Re: [sage-devel] Re: LazyPowerSeriesRing Replacement
That's a misunderstanding: I am NOT attached to the name LazyTaylorSeries(Ring). I would prefer that the ticket goes in with the name we agree on, rather than going in with a name that we deprecate in the same release. Moreover, I do not know whether there will be a conflict with the LazyPowerSeries(Ring) in the species directory, and I am somewhat unwilling to find out, because that code seems to have a few bugs and will be replaced anyway.

Re: [sage-devel] Re: LazyPowerSeriesRing Replacement
I will let Martin discuss the naming as I think the is attached to the name LazyTaylorSeries(Ring). A quick counterpoint to Kwankyu's claim, the power series "is" a function (well, formally), we just usually think of it as being equal to an "easier" function. However, it is meant to be a complete replacement with removing the old LazyPowerSeriesRing code. This new version should be faster, more robust, and have more functionality.

[sage-devel] Re: LazyPowerSeriesRing Replacement
If LazyTaylorSeriesRing could be a complete replacement of LazyPowerSeriesRing, then I think we should remove the old LazyPowerSeriesRing and rename LazyTaylorSeriesRing to LazyPowerSeriesRing. Do you mean this? Mathematically, Taylor series means power series derived from a function. So aTaylor series is always attached to a function. The name LazyTaylorSeriesRing seems a misnomer. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
