2012-02-03 08:34:31 +0200 | asked a question | weight orders I found that installed Sage on my VM Ubuntu can't create weighted TermOrders. Using 'Force = True' results in a ring with just lex order. Reinstalling doesn't help. Copying from http://sagemath.org/doc/reference/sag... results in Error massage: "verbose 0 (388: term_order.py, __init__) Term ordering 'wdegrevlex' unknown" how can i fix that problem? |
