I have two algebraic number fields QQ(alpha), QQ(beta), and I want to compute the smallest field containing both of these fields. The reason I need to do this is as follows:
I have matrix representations V1 of G1, and V2 of G2. V1 is given over QQ(alpha) and V2 is given over QQ(beta). I am looking to take their direct sum, so ideally what I would do is take the block diagonal matrices consisting of generators from V1 in the upper left and V2 in the lower right. The problem (as I see it) is that I need to find a common field to build this matrix space. I didn't see anything after a quick glance on the number fields documentation page-- whats the easiest way to get this done? -martin -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
