Series Rings
Removals and Changes:
- Some improvements have been made to Factorization of polynomials over
series rings.
- The integer ring or the field of fractions is now remembered by a series
ring.
New Features:
- Some of the basic arithmetic functions have been improved when
the result has high precision.
- Extensions of series rings can be constructed having unbounded precision.
- For elements of extensions of series rings IsUnit has been added.
Bug Fixes:
- Some precision handling has been improved for extensions of series
rings.
- The construction of an unramified extension by a polynomial not over the
coefficient ring of the series ring has been fixed. (V2.15-11)
- The computation of roots of a polynomial over a series ring with low
precision has been fixed. (V2.15-13)
- The coercion of rational functions into series rings over the integer ring
has been fixed. (V2.15-13)
