In other words, given, say, a polynomial in $x_0,y_0,x_1,y_1$, how can we output this polynomial under the map sending $y_i$ to $x_i^{-1}$? I'm specifically looking to apply this to Hall-Littlewood polynomials if that helps.rogervanpeskiMon, 27 Jul 2015 17:01:08 -0500http://ask.sagemath.org/question/28717/
