The plane overpartition, a two-dimensional version of the overpartition of an integer n, was introduced recently by Corteel, Savelief, and Vuletić. In the past, this plane overpartition has been studied as the “dotted plane partition” by Brenti, the “strict plane partition” by Vuletić, and the “BKP plane partition” by Foda and Wheeler. In this paper, we establish a strong asymptotic formula for the plane overpartition by giving arbitrarily long summands in the main term and explicit error estimates. In addition, we consider the k-th differences of the plane overpartition and provide a strong asymptotic for these differences. We show that these k-th differences are positive for any fixed k and satisfy higher-order Turán inequalities for any large integer n.

The Piltz divisor problem is a natural generalization of the classical Dirichlet divisor problem. In this paper, we study this problem over number fields and obtain improved Ω-bounds for its error terms. Our approach involves generalizing a Voronoi-type formula due to Soundararajan in the number field setting, and applying a recent result due to the second author.

We prove a new bound to the exponential sum of the form by a new approach to the Type I sum. The sum can be applied to many problems related to Piatetski-Shapiro primes, which are primes of the form . In this paper, we improve the admissible range of the Balog-Friedlander condition, which leads to an improvement to the ternary Goldbach problem with Piatetski-Shapiro primes. We also investigate the distribution of Piatetski-Shapiro primes in arithmetic progressions, Piatetski-Shapiro primes in a Beatty sequence and so on.
我们用I型和的一种新方法证明了形式为∑h ~ h δh∑m ~ m∑n ~ Nmn ~ xambne（αmn+h(mn+u)γ）的指数和的一个新界。这个和可以应用于许多与皮亚茨基-夏皮罗素数有关的问题，它是形式为⌊nc⌋的素数。本文改进了Balog-Friedlander条件的可容许范围，从而改进了带Piatetski-Shapiro素数的三元哥德巴赫问题。我们还研究了等差数列中的Piatetski-Shapiro素数的分布，Beatty数列中的Piatetski-Shapiro素数等。

In a letter from Tate to Serre dated March 26, 1974, Tate suggested a classification of weight one modular forms of prime level in terms of their associated odd Artin representations. This paper carries out an analogous classification of Maass wave forms of prime power level in terms of complex even representations. The parameters are identified with techniques from class field theory and Galois representations. The classification reveals that there exist distinct Maass cusp forms of tetrahedral type on that remain inequivalent modulo 3 for and 20887, and that these ℓ are the three smallest such primes.

In 2008, Wang & Wang showed that the set of gaps of a numerical semigroup generated by two coprime positive integers a and b is equidistributed modulo 2 precisely when a and b are both odd. Shor generalized this in 2022, showing that the set of gaps of such a numerical semigroup is equidistributed modulo m when a and b are coprime to m and at least one of them is 1 modulo m. In this paper, we further generalize these results by considering numerical semigroups generalized by geometric sequences of the form , aiming to determine when the corresponding set of gaps is equidistributed modulo m. With elementary methods, we are able to obtain a result for and all m. We then work with cyclotomic rings, using results about multiplicative independence of cyclotomic units to obtain results for all k and infinitely many m. Finally, we take an approach with cyclotomic units and Dirichlet L-functions to obtain results for all k and all m.
Wang &； Wang在2008年证明了当a和b都是奇数时，由两个素数正整数a和b生成的数值半群的间隙集精确地是等分布模2。Shor在2022年推广了这一结论，证明了当a和b对m互素且至少有一个是1模m时，这样的数值半群的间隙集是等分布模m。在本文中，我们进一步推广了这些结果，考虑了由ak，ak−1b，…，bk形式的几何序列广义的数值半群，目的是确定相应的间隙集何时是等分布模m。我们能够得到k=2和所有m的结果。然后我们使用环切环，使用关于环切单元乘法独立性的结果来获得所有k和无限多个m的结果。最后，我们采用环切单元和Dirichlet l -函数的方法来获得所有k和所有m的结果。
