A characterization of p-bases of rings of constants [PDF]
Open Mathematics, 2013 Abstract We obtain two equivalent conditions for m polynomials in n variables to form a p-basis of a ring of constants of some polynomial K-derivation, where K is a unique factorization domain of characteristic p > 0. One of these conditions involves Jacobians while the other some properties of factors.

Double Split-Ring Resonator for Dielectric Constant Measurement of Solids and Liquids [PDF]
Journal of Electromagnetic Engineering and Science, 2022 This study proposes a 2.45-GHz double split-ring resonator for measuring the dielectric constant in both solids and liquids. Two concentric rectangular rings with asymmetric splits are used in the proposed resonator to achieve a high-quality factor for ...

Rings of Constants of the Formk[f] [PDF]
Communications in Algebra, 2006 Let k[X] be the algebra of polynomials in n variables over a field k of characteristic zero, and let f ∊ k[X]∖ k. We present a construction of a derivation d of k[X] whose ring of constants is equal to the integral closure of k[f] in k[X]. A similar construction for fields of rational functions is also given.

Generators of rings of constants for some diagonal derivations in polynomial rings
Journal of Pure and Applied Algebra, 1995 Let \(K\) be a field of characteristic zero. The authors show that if \(n\geq 3\), that given \(r\geq 0\) there exists a diagonal \(K\)-derivation of \(K[x_1, \dots, x_n]\) such that the minimal number of generators over \(K\) of the ring of constants is equal to \(r\).

Subring of constants of a ring of characteristic p>0
Le Matematiche, 1993 Let A be a local ring of characteristic p>0 which has a p-basis over a subring C, and B be the subring of constants of A for a derivation (or derivations ) of A over C. We give a sufficient condition for B to have a p-basis over C. We add some examples.

Optical appearance of Einstein-Æther black hole surrounded by thin disk
Nuclear Physics B, 2022 In Einstein-Æther theory, the Lorentz symmetry is locally broken in the high-energy regime due to the presence of the Æther field. This shall leave significant imprint on astronomical observation.

Rings of constants of linear derivations on Fermat rings [PDF]
Communications in Algebra, 2018 In this paper we characterize all the linear $\mathbb{C}$-derivations of the Fermat ring. We show that the Fermat ring has linear $\mathbb{C}$-derivations with trivial ring of constants and construct some examples.
