Title |
: |
Combinatorial approach to the conjugacy-class algebra of the symmetric group |
| Abstract | : |
For A=(1)^{l_1}(2)^{l_2}...(n)^{l_n} a
conjugacy class in S_n, let Supp(A)=\Sum_{i=1}^n i\cdot l_i=n-l_1 Evaluation of the coefficient of the calss-sum C in the product of the class sums A and B is reduced to a combinatorial problem in S_k, where k=min{Supp(A),Supp(B),Supp(C)}. |
