Hi, I need to perform computations with linear differential operators whose coefficients are polynomials in several variables (in Euclean space). Has Sage some support for this kind of computation?
Could you suggest me some tool for doing that? For instance assume that you have two first order differentian operators (vector fields in the language of differential geometry) like X = x D_x - y D_y Y= x D_x - y D_z where D_x is the partial derivative with respect to x. I would like to compute XY [which is a second order operator], or things like the Lie bracket [X,Y]=XY-YX) [which is a first order one] many thanks, Pablo De Nápoli -- 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 URL: http://www.sagemath.org
