GSoC Week 7
So Far
PR 9575 and PR
9495 got merged this week. All the
basic functions are now in place in polys.ring_series
. The module supports
Laurent as well as Puiseux series expansion. The order of the day is to
extend this support for nested functions, and encapsulate the whole thing with
classes. The idea is that the user need not bother about calling ring_series
functions and that the class should hold all the relevant information about the
series.
Given that SymPy already has series
infrastructure, we need to decide whether
ring_series
with be integrated with it or whether it will be distinct from it.
Next Week

Discuss and decide how
ring_series
is to be used and write its classes accordingly. I will build upon PR 9614 
Write a
series
function that makes use ofring_series
functions to expand arbitrary expressions.
I also need to start porting some of it to Symengine. The basic polynomial
operations are in place there. I need to discuss with Ondrej and Sumith how the
series module will best work with the Polynomial module. If that is sorted, I
can start porting the ring_series
functions.
Cheers!
