Description
These combinatorial objects index the space of symmetric polynomials in two sets of variables, one commuting and one anticommuting, and they are known as symmetric functions in super space (hence the origin of the name super partitions).
Super partitions may be input in two different formats: one as a pair consisiting of fermionic (strict partition) and a bosonic (partition) part and as a list of integer values where the negative entries come first and are listed in strict order followed by the positive values in weakly decreasing order.
A super partition is displayed as two partitions separated by a semicolon as a default. Super partitions may also be displayed as a weakly increasing sequence of integers that are strict if the numbers are not positive.
