Hello, I would appreciate very much if somebody could add the following thing to the symmetric functions in sage. Mostly this is just a variant of the omega function, which is implemented by transposition of partitions in the schur basis. The point is that I just do not dare to do it myself... This would mean creating a patch, and I'm afraid I will be lost if I have two patches of my own. One is hard enough :)
My need : a function "f.suspension(t)" where f is a symmetric function and t is an element of the base ring. what it should do : in the Schur basis : it transposes the partition and multiply the coeff by (-t)**(n-1) where n is the size for example a=s([3,1]) b=a.suspension(t);b t**3*s([2,1,1]) Thanks for your help, Frederic -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
