How can I define a polynomial boolean ring in 'a' in which it holds that a+a=0 both cases: (1) when 'a' is an unknown parameter and (2) when 'a=1'. Please see below:
sage: A.<a> = BooleanPolynomialRing(1) sage: a a sage: A Boolean PolynomialRing in a sage: a+a 0 ------------------------------------------------> ok sage: a*a a-------------------------------------------------> ok sage: a+a+a a-------------------------------------------------> ok sage: a*a*a a-------------------------------------------------> ok sage: a=1 sage: a+a 2-------------------------------------------------> NOT ok: why is this not 0? --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
