Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies
Advanced Science, EarlyView.A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

Advanced Electronic Materials, EarlyView.Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Harmonic numbers, harmonic series and zeta function
Moroccan Journal of Pure and Applied Analysis, 2018 This paper reviews, from different points of view, results on Bernoulli numbers and polynomials, the distribution of prime numbers in connexion with the Riemann hypothesis. We give an account on the theorem of G. Robin, as formulated by J. Lagarias.

Arithmetic functions associated with infinitary divisors of an integer
International Journal of Mathematics and Mathematical Sciences, 1993 The infinitary divisors of a natural number n are the products of its divisors of the form pyα2α, where py is a prime-power component of n and ∑αyα2α (where yα=0 or 1) is the binary representation of y.

On Some Properties of the Hofstadter–Mertens Function
Complexity, 2020 Many mathematicians have been interested in the study of recursive sequences. Among them, a class of “chaotic” sequences are named “meta-Fibonacci sequences.” The main example of meta-Fibonacci sequence was introduced by Hofstadter, and it is called the ...

Symmetric colorings of G × Z_2
Electronic Journal of Graph Theory and Applications, 2023 Let G be a finite group and let r ∈ N. An r-coloring of G is any mapping χ : G → {1, …, r}. A coloring χ is symmetric if there is g ∈ G such that χ(gx−1g)=χ(x) for every x ∈ G. We show that if f(r) is the polynomial representing the number of symmetric r-

Biquadratic Transformations for Checking the Hurwitz Stability via the Schur Stability
Asian Journal of Control, EarlyView.ABSTRACT Bilinear transformations such as the Möbius transformation have been used to study Hurwitz stability by means of Schur stability, or vice versa. However, the use of a well‐known Möbius transformation has pathological cases, hence Jalili–Kharaajoo and Araabi investigated and found a biquadratic transformation to study Schur stability by means ...

Fractal and Fractional, 2021 In 2021, Mork and Ulness studied the Mandelbrot and Julia sets for a generalization of the well-explored function ηλ(z)=z2+λ. Their generalization was based on the composition of ηλ with the Möbius transformation μ(z)=1z at each iteration step ...

Business Strategy and the Environment, EarlyView.ABSTRACT The relationship between eco‐innovation (EI) and firm performance (FP) is central to environmental management research, yet empirical evidence remains fragmented and highly context dependent. This article presents a global systematic literature review (SLR) of 541 empirical studies (2006–April 2025) to (i) diagnose the systematic sources of ...
