... of partitions (λ, µ) such that |λ|+|µ| = m. Their proof is based on construction of a bijection between the set of partitions of n with the sum of even parts being equal to m and a pairs of partitions ... q(m) can be also described as a number of colored partitions of m with b j possible colors for parts j. We call these partitions (b j ) j≥1 -colored partitions. Theresult of [...
