2014-02-02 17:43:47 -0600 | commented answer | converting a set into a list? @ndomes But it keeps only one 1 in the list.But i want to write set([1,1,2,2,2,3,4,5]) in partition form.That means i want output to be the list [5,4,3,2,2,2,1,1].Could you please tell me how to do it? |

2013-06-26 08:30:52 -0600 | asked a question | writting a code for finding the kostant partition function How to write a code for finding the kostant partition function for the elements of root lattice of rank 1 affine lie algebra $A_{1}^{(1)}$ which is defined as follows: $K(\beta)$ = the co-efficient of $e^{\beta}$ in $\prod _{\alpha \in \bigtriangleup}(1-e^{\alpha})$ where $\bigtriangleup$ is the set of positive roots of $A_{1}^{(1)}$ and $\beta$ is an element of the root lattice ? |

2013-05-04 00:17:57 -0600 | commented answer | solving a set of equations involving both inequalities and equalities sorry for the inconvenience.Actually i want to find all the lattice points of the polytope given by 20 equations.since i can not write all those 20 equations,hence i wanted to know if there is any code with which i can write equations in stead of tuples. |

2013-05-03 21:34:54 -0600 | commented answer | solving a set of equations involving both inequalities and equalities Is there any way to define polyhedron in terms of equations rather than points since the number of equations and number of variables might be too large in which case it would not be possible to write all equations in terms of tuples.? |

2013-03-28 07:32:13 -0600 | asked a question | code for bipartite graphs How to write a code for obtaining a bipartite graph where the edges are indexed by some numbers?e.g if i write the code as D = DiGraph({ 0: [1,2,3], 1: [0,2], 2: [3], 3: [4], 4: [0,5], 5: [1] }) then only graph is coming but the edges are not indexed here.How should i modify this so that edges of the graph will be indexed? |
