Irreducible numerical semigroups [PDF]
Pacific Journal of Mathematics, 2003 A numerical semigroup is said to be irreducible whenever it can not be expressed as an intersection of two numerical semigroups containing it properly. The paper under review studies several aspects of these semigroups. In Section 1, the authors give a characterization of irreducible semigroups in terms of their Frobenius number.

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets
Advanced Science, EarlyView.RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.

Note on irreducibility testing
, 1980 An effective method is developed for deducing the irreducibility of a given polynomial with integer coefficients from a single occurrence of a prime value of that polynomial.

Advanced Science, EarlyView.This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

Ergodicity of the two-dimensional magnetic Benard problem
Electronic Journal of Differential Equations, 2016 We study the two-dimensional magnetic Benard problem with noise, white in time. We prove the well-posedness including the path-wise uniqueness of the generalized solution, and the existence of the unique invariant, and consequently ergodic, measure ...

Ab Initio Thermoelectric Transport Calculations of Alloyed Half‐Heuslers
Advanced Science, EarlyView.The effect of alloying on the electronic transport of half‐Heusler thermoelectric materials is explored using a fully ab initio approach. A novel method is developed that combines calculations of alloyed supercells with Boltzmann transport, considering the full energy and momentum dependent scattering processes from first principles extracted ...

A generalization of Eisenstein-Schönemann irreducibility criterion
, 2010 One of the results generalizing Eisenstein Irreducibility Criterion states that if φ(x) = anxn+ an-1xn-1 +...+ a0 is a polynomial with coefficients from the ring of integers such that a s is not divisible by a prime p for some , each a i is ...

Advanced Electronic Materials, EarlyView.Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.
