We characterize the square-integrable representations of (connected, simply connected) solvable Lie groups in terms of the generalized orbits of the coadjoint action. We prove that the normal representations corresponding, via the Pukánszky correspondence, to open coadjoint orbits are type I, not necessarily square-integrable representations. We show that the quasi-equivalence classes of type I square-integrable representations are in bijection with the simply connected open coadjoint orbits, and the existence of an open coadjoint orbit guarantees the existence of a compact open subset of the space of primitive ideals of the group. When the nilradical has codimension 1, we prove that the isolated points of the primitive ideal space are always of type I. This is not always true for codimension greater than 2, as shown by specific examples of solvable Lie groups that have dense, but not locally closed, coadjoint orbits.
我们根据共轭作用的广义轨道来描述（连通的、简单连通的）可解李群的可方整表示。我们证明，通过普卡恩斯基对应关系，与开放共轭轨道相对应的正则表达式是 I 型，而不一定是平方可整合表达式。我们证明了 I 型方整表示的准等价类与简单连接的开放共轭轨道是双射的，而开放共轭轨道的存在保证了群的原始理想空间的紧凑开放子集的存在。当无根性的标度为 1 时，我们证明了基元理想空间的孤立点总是 I 型的。当标度大于 2 时，情况并非总是如此，这一点可以通过具有致密但非局部封闭的共轭轨道的可解李群的具体例子来证明。

An RD-space 𝑀 is a space of homogeneous type in the sense of Coifman and Weiss with the additional property that a reverse doubling property holds in 𝑀. In this paper, firstly, the authors give the Plancherel–Pôlya characterization of product weighted Triebel–Lizorkin spaces and product weighted Besov spaces on RD-spaces and make some estimates for the product singular integral operators in Journé’s class on these function spaces. As a result of these conclusions, they present some sufficient conditions for the boundedness of product singular integral operators on the product Lipschitz spaces and product weighted Hardy spaces. Secondly, by the boundedness of lifting and projection operators, they also obtain that the dual spaces of the product weighted Hardy spaces are product weighted Carleson measure spaces. Using the idea of dual, the authors obtain the weighted boundedness of singular integral operators on the product weighted Carleson measure spaces.

In 2004, Thakur introduced a positive characteristic analogue of multizeta values. Later, in 2017, he mentioned the two colored variants which are positive characteristic analogues of colored multizeta values in his survey of multizeta values in positive characteristic. In this paper, we study one of those two variants. We establish their fundamental properties, that include their non-vanishing, sum-shuffle relations, 𝑡-motivic interpretation and linear independence. For the linear independence results, we prove that there are no nontrivial k̄overline{k}-linear relations among the colored multizeta values with different weights.

In 1769, Euler proved the following result: ∫0π2log(sinθ)𝑑θ=-π2log2.int_{0}^{frac{pi}{2}}log(sintheta),dtheta=-frac{pi}{2}log 2. In this paper, as a generalization, we evaluate the definite integrals ∫0xθr-2log(cosθ2)𝑑θint_{0}^{x}theta^{r-2}logbiggl{(}cosfrac{theta}{2}biggr{)},dtheta for r=2,3,4,…r=2,3,4,dots . We show that it can be expressed by the special values of Kurokawa and Koyama’s multiple cosine functions 𝒞r(x
Given a proper holomorphic surjective morphism f:X→Y{f:Xrightarrow Y} between compact Kähler manifolds, and a Nakano semipositive holomorphic vector bundle E on X, we prove Kollár-type vanishing theorems on cohomologies with coefficients in Rqf∗(ωX(E))⊗F{R^{q}f_{ast}(omega_{X}(E))otimes F}, where F is a k-positive vector bundle on Y. The main inputs in the proof are the deep results on the Nakano semipositivity of the higher direct images due to Berndtsson and Mourougane–Takayama, and an L2{L^{2}}-Dolbeault resolution of the higher direct image sheaf Rqf∗(ωX(E)){R^{q}f_{ast}(omega_{X}(E))}, which is of interest in itself.

In this paper we prove some generalizations of the classical Hasse–Davenport product relation for certain arithmetic factors defined on a p-adic field F, among them one finds the ϵ-factors appearing in Tate’s thesis. We then show that these generalizations are equivalent to some representation theoretic identities relating the determinant of ramified local coefficients matrices defined for coverings of SL2(F){mathrm{SL}_{2}(F)} to Plancherel measures and γ-factors.

We give some q-supercongruences from a q-analogue of Watson’s F23{{}_{3}F_{2}} summation and the method of “creative microscoping”, introduced by the author and Zudilin. These q-supercongruences may be considered as further generalizations of the (A.2) supercongruence of Van Hamme modulo p3{p^{3}} or p2{p^{2}} for any odd prime p. Meanwhile, we confirm a supercongruence conjecture of Wang and Yue through establishing its q-analogue.

For a given normalized newform f of large prime level, we establish a lower bound with respect to the level for the number of normalized newforms g of the same weight and level as of f such that the central L-values of f and g both twisted by a quadratic character do not vanish.
对于给定的大素数级的规范化新形 f，我们为与 f 具有相同权重和级数的规范化新形 g 的数量建立了一个与级数相关的下限，使得 f 和 g 的中心 L 值都不会因二次方特征的扭曲而消失。

Given a prime power q and a positive integer n, let 𝔽qn{mathbb{F}_{q^{n}}} represent a finite extension of degree n of the finite field 𝔽q{{mathbb{F}_{q}}}. In this article, we investigate the existence of m elements in arithmetic progression, where every element is primitive and at least one is normal with prescribed norms. Moreover, for n≥6{ngeq 6}, q=3k{q=3^{k}}, m=2{m=2} we establish that there are only 10 possible exceptions.
给定一个质幂 q 和一个正整数 n，让 𝔽 q n {{mathbb{F}_{q^{n}}} 表示有限域 𝔽 q {{mathbb{F}_{q}}} 的 n 阶有限扩展。本文将研究算术级数中是否存在 m 个元素，其中每个元素都是基元，且至少有一个元素是具有规定规范的正则元素。此外，对于 n ≥ 6 {ngeq 6} , q = 3 k {q=3^{k}} , m = 2 {m=2 , m = 2 {m=2}，我们可以确定只有 10 个可能的例外。
