Some asymptotics for cranks

Inequalities and asymptotics for some moment integrals

For [Formula: see text], we obtain two-sided inequalities for the moment integral [Formula: see text]. These are then used to give the exact asymptotic behavior of the integral as [Formula: see text]. The case [Formula: see text] corresponds to the asymptotics of Ball's inequality, and [Formula: see text] corresponds to a kind of novel "oscillatory" behavior.

Asymptotics of Zeros for Some Entire Functions

We study the asymptotics of zeros for entire functions of the form sin z+ ∫ 1 −1 f(t)e dt with f belonging to a space X →֒ L1(−1, 1) possessing some minimal regularity properties.

Asymptotics of Some Convolutional Recurrences

We study the asymptotic behavior of the terms in sequences satisfying recurrences of the form an = an−1 + n−d k=d f(n, k)akan−k where, very roughly speaking, f(n, k) behaves like a product of reciprocals of binomial coefficients. Some examples of such sequences from map enumerations, Airy constants, and Painlevé I equations are discussed in detail. 1 Main results There are many examples in the ...

Cranks and T -cores

New statistics on partitions (called cranks) are defined which combinatorially prove Ramanujan’s congruences for the partition function modulo 5, 7, 11, and 25. Explicit bijections are given for the equinumerous crank classes. The cranks are closely related to the t-core of a partition. Using q-series, some explicit formulas are given for the number of partitions which are t-cores. Some related...
