Ticket #18514 – Description
v197 v198 5 5 In the experimental version 2.1.5, I have improved the computation of Poincaré series, depth and filter degree type (the latter now uses a Hilbert-driven computation of Gröbner bases in elimination order, which works since in that setting the Hilbert function is easily available), and I added new functionality related with nilpotency. 6 6 7 Package structure 8 ================= 7 '''__Package structure__''' 9 8 10 9 Version 3.0 is refactored as follows: … … 17 16 - The documentation is built in an improved way. 18 17 19 Further changes 20 =============== 18 '''__Further changes__''' 21 19 22 20 - The custom logging in the old spkg is replaced by Python's logging module. … … 27 25 Many tests have changed, since the ring presentations of the computed cohomology rings, specifically for non-primepower groups, have changed. I do not fully understand ''why'' they changed. but it seems that it is a consequence of changes in Singular. The changes did (of course...) not affect the isomorphism types of the rings. 28 26 29 ''' Upstream tar ball'''27 '''__Upstream tar ball__''' 30 28 31 29 http://users.minet.uni-jena.de/cohomology/p_group_cohomology-3.0.tar.gz
