[sage-support] if I input 1.1, why is it real not rational?
I would like to understand Sage behaviour better. I just found out that Sage is different from Pari when it comes to user input of values: sage: Ei(1.1).n(100) 2.1673782795634028985887198360 sage: Ei(11/10).n(100) 2.1673782795634028235837873423 while in Pari: ? sin(1.1) %1 = 0.89120736006143533995180257787170353832 ? sin(11/10) %2 = 0.89120736006143533995180257787170353832 What could be the reason to interpret the user input 1.1 as real with precision of 53 bits instead of short way of specfying 11/10? Programming convenience? If you say well then the user should say 11/10 if she means it, this could be said as well with RealField(1.1), so what is the reason for this convention?

Re: [sage-support] if I input 1.1, why is it real not rational?
Hello. I do not think that is really a convention, but it is very logical because 1.1 can also be a float result given by Python. But floats and decimals are not the same due to the ways operators act on them.

Re: [sage-support] using s_integral_points to get the rank of an elliptic curve

You would have to ask the Magma people about that, but the implementations are entirely independent.

It is taking me longer than I expected to review a long-lived patch on the trac server which translates an implementation by another student of mine of integral points over number fields (not S-integral points yet) from its original Magma form to Sage; there are some good reasons for this, as some of the published formulas are wrong! Your enquiry gives me motivation to get back to that project which has been lying neglected since term started in January!

[sage-support] Re: graph.trace_faces() gives me inconsistent results
Nathann, Thanks for your help! I'm fairly new to both Sage and graph theory, but I understand the difference you point out, and it looks like the trace faces function is giving me accurate faces for some valid planar embedding- just not the one I thought it was working on. I spoke with a colleague yesterday, and he helped come up with a solution. He tried to post his results on this board, but I'm not seeing it, so I'm copy/pasting his solution here. This is not the most efficient solution, but I've tested in on a variety of real planar graphs, and it does work. Ethans answer: the problem is not their algorithm for finding faces, but the embedding. The embedding should be a clockwise ordering of nodes, but if you look, node 3's neighbors list in the embedding (s_emb[3]) is not clockwise. If you reorder the nodes, it seems to work. See below. import numpy def reorder_embedding(emb, locs): new_emb = {} for i,neighbors in emb.iteritems(): def angle(b): dx = locs[b][0] - locs[i][0] dy = locs[b][1] - locs[i][1] return numpy.arctan2(dx,dy) reorder_neighbors = sorted(neighbors, key=angle) new_emb[i] = reorder_neighbors return new_emb S = Graph(lat) S.show(vertex_size = 600, pos = nodes_dict) S.is_planar(set_embedding = True) s_emb = S.get_embedding() s_emb_r = reorder_embedding(s_emb, nodes_dict) print SAGE embedding:, s_emb print Reordered:, s_emb_r faces = S.trace_faces(s_emb) print SAGE faces:, faces faces_r = S.trace_faces(s_emb_r) print Reordered:, faces_r -- You received this message because you are subscribed to the Google Groups sage-support group.

Re: [sage-support] Re: graph.trace_faces() gives me inconsistent results
Christa, The problem is not with the code, but your expectations of it (which may be valid, but that would be a feature request and not a bug). You expect the code to look at your planar position dictionary, and gin up an embedding from that. That is not a bad idea, and possibly a good feature to request. What is actually happening is that you are asking the code to make a new embedding, and compute the faces from that embedding. It is not the same embedding as the one you want. If you gave it a 3-connected planar graph, of course, the embedding (hence faces) would be unique (up to orientation)... but your graph is not 3-connected. To see the embedding those faces correspond to, try S.is_planar(set_embedding = True, set_pos=True) S.show() Regards, Tom On Fri, Mar 28, 2014 at 9:24 AM, Christa Brelsford christa.brelsf...@gmail.com wrote: Nathann, Thanks for your help!

-- Forwarded message -- From: aperry ape...@math.harvard.edu Date: Fri, Mar 28, 2014 at 5:25 PM Subject: sage bug To: wst...@uw.edu Hi, I'd like to report a bug in sage. There seems to be a problem with the functions that check whether two quadratic forms over Z are equivalent. Here is a sample of code that doesn't work correctly: Q1 = QuadraticForm(ZZ, 3, [-4,6*2,-2*2,-10,3*2,2]) Q2 = QuadraticForm(ZZ,3,[-14,9*2,34*2, -6, -21*2, -82]) Q3 = QuadraticForm(ZZ,3,[-14,9*2,34*2, -6, -21*2, -822]) [Q1.hasse_invariant(p) for p in prime_range(300)] [Q2.hasse_invariant(p) for p in prime_range(300)] [Q3.hasse_invariant(p) for p in prime_range(300)] Q1.is_globally_equivalent__souvigner(Q2) Q1.is_globally_equivalent__souvigner(Q3) Q1.is_globally_equivalent_to(Q2) Q1.is_globally_equivalent_to(Q3) Output: [-1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1] [-1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1] [1, -1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1] True True Error in lines 9-9 Traceback (most recent call last): File /projects/2d4ad217-a078-4d67-9d8b-0bf2c928d95d/.sagemathcloud/sage_server.py, line 733, in execute exec compile(block+'\n', '', 'single') in namespace, locals File , line 1, in module File /usr/local/sage/sage-6.2/local/lib/python2.7/site-packages/sage/quadratic_forms/quadratic_form__equivalence_testing.py, line 177, in is_globally_equivalent_to raise ValueError, not a definite form in QuadraticForm.is_globally_equivalent_to() ValueError: not a definite form in QuadraticForm.is_globally_equivalent_to() Some comments: 1. As the computation of the Hasse invariants show, Q1 and Q2 are equivalent over the rationals (you can check they have the same signature too), but Q3 is not equivalent to Q1. 2. Yet is_globally_equivalent__souvigner says that all of the forms are equivalent over Z, which is false. It seems that this function always returns true. 3. is_globally_equivalent_to should work for indefinite forms (such as Q1 and Q2), but it gives an error message saying something about the forms not being definite. 4. What I originally wanted to compute with this was the actual matrix conjugating Q1 to Q2 over Z (I do believe they are equivalent over Z). Sage should return this matrix with say Q1.is_globally_equivalent__souvigner(Q2, True), but this crashes.

[sage-support] sage notebook in other browser
My default browser is firefox when i type *$ sage -notebook *it opens in firefox. Is there a way to specify other browser like *chromium-browser* -- You received this message because you are subscribed to the Google Groups sage-support group.

Thank You Very much. Now I will be able to make a unity launcher for sage. -- You received this message because you are subscribed to the Google Groups sage-support group.
