Infinite Easier Waring Constants for Commutative Rings
Topology and its Applications, 2010 Suppose n >= 2. We show that there is no integer v >= 1 such that for all commutative rings R with identity, every element of the subring J(2^n,R) of R generated by 2^n-th powers can be written in the form \pm f_1^{2^n} \pm \cdots \pm f_v^{2^n} for some f_1,...,f_v \in R and some choice of signs.

On the variety associated to the ring of theta constants in genus 3 [PDF]
American Journal of Mathematics, 2016 Due to fundamental results of Igusa and Mumford the $N=2^{g-1}(2^g+1)$ even theta constants define for each genus $g$ an injective holomorphic map of the Satake compactification $X_g(4,8)=H_g/ _g[4,8]$ into the projective space $P^{N-1}$. Moreover, this map is biholomorphic onto the image outside the Satake boundary.

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.

Constant-Beamwidth Beamforming with Concentric Ring Arrays [PDF]
Sensors, 2021 Designing beampatterns with constant beamwidth over a wide range of frequencies is useful in many applications in speech, radar, sonar and communication. In this paper, we design constant-beamwidth beamformers for concentric ring arrays. The proposed beamformers utilize the circular geometry to provide improved beamwidth consistency compared to ...

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.
