2015-04-16 20:42:53 +0200	commented answer	Is Einstein notation available in sage? Dear Eric, 1) I must to thanks for your attention. 2) I saw the details link you mentioned. Your theory is very good. because I deal with vector spaces as very special modules. It works and seems flexible in computations. But, here is a problem for me. Since I am working with tensors symbolically, I need to recognizing no fixed dimension. Cadabra serves this very good for me. But, I like to do all of my computation with sage and python only.

2015-04-16 00:26:15 +0200	asked a question	Is Einstein notation available in sage? Dear all I searched here. But I can not find a contented answer. There is a very usable notation in summations simplifying computations inclusive very $\Sigma$. Is there a way in Sage that I can use this kind of notation? For more information, this notation is worked out in Cadabra.

2015-04-14 18:04:19 +0200	asked a question	A confusing syntax error when using elif Dear All This is my confusing problem: `sage: m=31 sage: if m%3==0: ....: print m/3 ....: elif m%3==1: ....: print (m-1)/3 ....: File "<ipython-input-2-ec9f38b42615>", line 3 elif m%Integer(3)==Integer(1): ^ SyntaxError: invalid syntax sage:` I do not copy-paste the code. I have ubuntu14.04 and my sage version is 6.5.
