Kostka polynomials #14

Closed schto223 closed 3 years ago

schto223 commented 3 years ago

---Partitions.jl--- -added setindex! for Partitions since this is usefull when using Partitions to work with Tableaux.

-added dominates(lambda,mu) which defines an ordering over Partitions of the same number

---runtests.jl--- -added tests for semistandard_tableaux and standard_tableaux

---tableaux.jl--- -replaced all instances of deepcopy by a much more efficient code

-added: semistandard_tableaux(s,weight) standard_tableaux(s) standard_tableaux(n) hook_length(Tab,i,j) hook_length(s,i,j) hook_length_formula(s) schur_polynomial(shp) weight(Tab) reading_word(Tab) charge(Tab) charge(word) kostka_polynomial(lambda,mu)

-reordered a few functions in tableaux.jl
