Moving Sum Procedure for Multiple Change Point Detection in Large Factor Models
ABSTRACT This paper proposes a moving sum methodology for detecting multiple change points in high‐dimensional time series under a factor model, where changes are attributed to those in loadings as well as emergence or disappearance of factors. We establish the asymptotic null distribution of the proposed test for family‐wise error control and show the

The distribution of \(\alpha p\) modulo one
Let \(\|x\|\) be the distance from \(x\) to the nearest integer, and let \(\alpha\) be an irrational number. Then the authors prove that for any \(\varepsilon> 0\) there are infinitely many prime numbers \(p\) such that \(\|\alpha p\|< p^{-16/49+ \varepsilon}\), improving the value \(9/28\) of \textit{C. Jia} [Sci. China, Ser.

On the exceptional set in Littlewood's discrete conjecture
Abstract We consider a discrete analogue of the well‐known Littlewood conjecture on Diophantine approximations and obtain a strong upper bound for the number of exceptional vectors in this conjecture.

On the distribution of αp+β modulo one
Abstract Let ‖ ⋅ ‖ denote the minimum distance to an integer. For 0 γ 1 , θ > 0 and ( α , β ) ∈ R ∖ { 0 } × R we study when ‖ α p γ + β ‖ p − θ , holds for infinitely many primes p of a special type.

Quadratic non-residues and non-primitive roots satisfying a coprimality condition
Let $q\geq 1$ be any integer and let $ \epsilon \in [\frac{1}{11}, \frac{1}{2})$ be a given real number. In this short note, we prove that for all primes $p$ satisfying $$ p\equiv 1\pmod{q}, \quad \log\log p > \frac{\log 6.83}{\frac{1}{2}-\epsilon} \mbox{

On Uniform Distribution Modulo 1 and Functional Convergence
Abstract In this note, we study the convergence of functional sequences. A criterion for uniform distribution mod 1 is derived. Then we study the partitions, block sequences and the uniform distribution preserving mappings. In the last part, we prove that to each one to one sequence dense in [0, 1] a regular matrix summation method such ...

A linearized stabilizer formalism for systems of finite dimension
The stabilizer formalism is a scheme, generalizing well-known techniques developed by Gottesman [quant-ph/9705052] in the case of qubits, to efficiently simulate a class of transformations ("stabilizer circuits", which include the quantum Fourier ...
