Arbitrary-peak conjecture for rank-generating functions
Arbitrary-peak conjecture for rank-generating functions
Let be the rank-generating function for partitions contained inside a partition . A polynomial is unimodal if its coefficients weakly increase and then weakly decrease; a peak is a local maximum in its coefficient sequence. Arbitrary-peak conjecture. For every integer , there exists a partition such that is nonunimodal with (exactly?) peaks. The parenthetical qualification is part of the source statement, so it is unclear whether the intended assertion is exactly peaks or merely peaks; no resolution is supplied.
