متن کاملOn a mysterious partition identity
(1.1) Notation. Let Pn denote the set of all partitions of n ∈ N0. For λ ∈ Pn let l(λ) ∈ N0 be its length, i. e. the number of its non-zero parts λ1 ≥ λ2 ≥ . . . ≥ λl(λ) > 0. Furthermore, let s(λ) := n− l(λ) ∈ N0 be its generalized sign, thus we have sgn(λ) = (−1). We also write λ = [11, . . . , nn], where ai(λ) ∈ N0. Let Sn denote the symmetric group on n ∈ N0 letters. For λ ∈ Pn let Cλ ⊆ Sn d...
