According to them, 1-distinct and 2-distinct partitions of n are equinumerous with partitions of n into parts congruent to \u00b11 modulo 4 and partitions of n into parts congruent to \u00b11 modulo 5, respectively. Furthermore, their generating functions are modular functions up to multiplication by rational powers of q. For d \u2265 3, however, there is neither the same type of partition identity nor modularity for d-distinct partitions. Instead, there are partition inequalities and mock modularity related with d-distinct partitions. For example, the Alder-Andrews Theorem states that the number of d-distinct partitions of n is greater than or equal to the number of partitions of n into parts which are congruent to \u00b11 (mod d+3). In this note, we present the recent developments of generalizations and analogs of the Alder-Andrews Theorem and establish asymptotic lower and upper bounds for the d-distinct partitions. Using the asymptotic relations and data obtained from computation, we propose a conjecture on a partition inequality that gives an upper bound for d-distinct partitions. Specifically, for d \u2265 4, the number of d-distinct partitions of n is less than or equal to the number of partitions of n into parts congruent to \u00b11 (mod m), where m \u2264 2d\u03c0^2 \/ [3 log^2 (d)+6 log d] ."},"keywords":[["asymptotic formulas"],["partition inequalities"],["partition identities"],["d-distinct partitions"],["partitions"],"2010 Mathematics Subject Classification. 11P82, 11P84","[MATH]Mathematics [math]"]}
