I checked some examples of laurent series expansion and the series function seems to give correct results. Some examples I tested where from -
1. http://courses.washington.edu/ph227814/228/W14/notes/Laurent.nb.pdf 2. https://piazza.com/class_profile/get_resource/iw9kxycftxk6su/iy5oz4r144i6rr 3. https://www.maplesoft.com/support/help/Maple/view.aspx?path=numapprox/laurent Naveen On Thursday, March 25, 2021 at 9:27:47 AM UTC+5:30 Naveen Saisreenivas Thota wrote: > > Is the Laurent series actually needed? > > > I haven't read the paper but I looked at algorithm 11.
