Component: | singular-kernel | Version: | |
Keywords: | SCA, std, bba | Cc: |
Description
the result of std(std(0), xy + z) is wrong in an exterior algebra (in variables: x,y,z).
seems to be due to special implementation of bba in SCA.

my results for the test. (bug only in Exterior algebra... not in a factor algebra!)

primary entry point is jjSTD_1. further calls: -> kStd -> nc_GB.
Main difference is due to: int strat->newIdeal (position of additional poly/vector in F) It seems that it will be handled transparently by initBuchMora and other shadow procedures backing bba...
Hmm... what does TEST_OPT_SB_1 mean?

this was quite a deal... have found a bug in enterSSpecialPairs (clearS was disabled for non-commutative rings). seems to work now... would be nice to test.
