Few remarks:
- you write about reconstructing factors via Pade aproximation.
This is in fact called Hermite-Pade problem (Pade would be in case
of first order factor). FriCAS contains routine to solve
Hermite-Pade problem. In fact 'guessHolo' routine (maybe after
a small modification) should do.
- concerning 'nm_mult' routine I do not undertand what is the
purpose. If you need computations on operatiors written in
terms of xD, then the domain I provided and convertion routines
you wrote should do. In particular multiplication of operators
written in term of 'xD' should be just '*'.
- what 'ramification_of' should do? Is it the substitution
from end of page 19 in van Hoej thesis?
- could you say more precisely what 'coefs_operator' should do?
- in chapter 2 van Hoej writes about exponential parts, then
in chapter 3 about very similar notion of generalized exponents.
Later developements showed that generalized exponents are more
important. I think you should provide routine to compute
generalized exponents (it should probably just take part of
result returned by 'factor_riccati').
