Something similar to the one done in mathematica that is the function InterpolatePolynomial. In one variable there is the function in sage called .lagrange_polynomial which works pretty good. I was wonder if there is something in multivariable ? 2016-06-15 21:00:50 -0600 asked a question coefficient function in sage I want to compute the coefficient of certain polynomial but he coefficient function in sage gives me back for the coefficient of X^0 that is for any polynomial f f.coefficient(x^0) = 0 Can you some suggest how to change this thing in sage library ? 2016-06-13 19:37:37 -0600 asked a question evaluation of character of symmetric group. I am writing a code in sage where I am using character of Symmetric group. I want to evaluate the character of symmetric group on certain conjugacy classes. While I know the command for defining character as below.\ G = SymmetricGroup(3)\ rho = SymmetricGroupRepresentation([1,1,1])\ chi = rho.to_character(); I want to find chi([2,1]) that is to evaluate chi on the conjugacy class of type (2,1). Any help please ? 2016-06-13 19:35:20 -0600 received badge ● Scholar (source) 2016-05-03 08:09:07 -0600 asked a question What is the bug ? I am writing this code in sage online worksheet given a tuple say $a=(a_1,a_2,...a_n)$ \phi be an permutation in S_n then \phi(a)= (a_\phi(1),...,a_\phi(n)) I want to count the number of permutation that fixes a The code is as follows def Aut(tuple): c=1 for a in SymmetricGroup(len(tuple)): if a.action(tuple)== tuple : c=c+1 2016-05-03 08:09:06 -0600 asked a question What is the bug I am writing this code in sage online worksheet given a tuple say $a=(a_1,a_2,...a_n)$ \phi be an permutation in S_n then \phi(a)= (a_\phi(1),...,a_\phi(n)) I want to count the number of permutation that fixes a The code is as follows def Aut(tuple): c=1 for a in SymmetricGroup(len(tuple)): if a.action(tuple)== tuple : c=c+1 return c
