In quantum physics, one needs to work with quantum operator that are non-commuting objects. There, we often need to check whether commutator or anti-commutator of two composite operators are zero or not. An example session would be: ---------- sage: A,B = nc_var('A,B') sage: a,b,c,d = var('a,b,c,d') sage: C = a*A + b*A*A sage: D = d*B sage: commutator(C, D) a*d*commutator(A,B) + b*d*A*commutator(A,B) + b*d*commutator(A,B)*A sage: commuator.define([A,B], 1) sage commutator(A, B) 1 sage: commutator(C,D) a*d + 2*b*d*A ------------ Thanks, Golam --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
