Craig–Pun's log-concavity and higher-order Turán conjecture for distinct partitions
Let denote the number of partitions of into distinct parts. Log-concavity means , and the higher-order Turán inequalities are the corresponding higher-order inequalities for this sequence.
Craig–Pun's conjecture. The function is log-concave for and satisfies the higher-order Turán inequalities for .
The paper presents this as a conjecture of Craig and Pun. Its status is not resolved in the supplied material, although the paper notes that the higher-order inequalities hold for sufficiently large .
