Aug28 asked How to output an expression to an external file in “plain text” format without breaking lines? Jun20 comment How to Simplify equations over a Ring with Mathematica? Cool. Is there any way to work over Ring of rational numbers QQ? Thanks. Jun20 accepted How to Simplify equations over a Ring with Mathematica? Jun20 comment How to Simplify equations over a Ring with Mathematica? Nice. But it seems that the option Modulus is not capable to use with Simplify or FullSimplify. I don't want to solve the equations, but just want to simplify the relations of equations. Any idea? Jun19 accepted How to do substitution of variable with power in Mathematica? Jun19 asked How to Simplify equations over a Ring with Mathematica? Jun19 comment How to do substitution of variable with power in Mathematica? cool. I just edited my original post with more details. It seems when I use ToExpression["la_1la_2"], MMa will treat l and a_i as separate variables, but I want to treat la as one variable. Any idea?

Jun12 comment Any efficient way to make complete homogeneous symmetric functions in Mathematica? The only little issue is 0-th order is not well defined, i.e. completeSymmetricPolynomial[0, {a, b, c, d}] Jun12 comment What alternative notation of subscripts/superscripts that are also treated as SYMBOLS in Mathematica? Nice. Thank you.
