ON THE GRADED RING OF THETA-CONSTANTS.*

American Journal of Mathematics, 1964
Introduction. Let g be a positive integer and let T be a complex symmetric matrix of degree g with a positive-definite imaginary part. The set of such matrices forms a convex open subset of the 1 * g (g + 1) -dimensional complex vector space and (as a ...

Shirshov finiteness over rings of constants

Algebra and Logic, 1997
The author studies rings of constants for restricted differential Lie algebras acting on prime rings and having nontrivial quasi-Frobenius inner part. It is shown that, under this restriction, Shirshov's local finiteness correspondence exists between a given prime ring \(R\) and the ring of constants \(R^L\).

Remarks on rings of constants of derivations II

Communications in Algebra, 1992
Let k be a field of characteristic p>0 and D≠0 a family of k-derivations of k[x,y]. It is proved in [1] that k[x,y]D, the ring of constants with respect to D, can be generated, as a k[x p,y p]-algebra, by p - 1 elements.

Nonlocal dual-phase-lag thermoelastic damping in small-sized circular cross-sectional ring resonators

Mechanics of Advanced Materials and Structures, 2023
The purpose of current research is to establish a theoretical size-dependent framework for estimating the amount of thermoelastic damping (TED) in miniaturized rings with circular cross section via the nonlocal dual-phase-lag (NDPL) generalized ...

A Machine Learning Approach for Rate Constants II: Clustering, Training, and Predictions for the O(3P)+HCl -> OH+Cl Reaction.

Journal of Physical Chemistry A, 2020
Following up on our recent paper which reported a machine learning approach to train on and predict thermal rate constants over a large temperature range, we present new results by using clustering and new Gaussian process regression on each cluster ...

3-D-Printed Wideband Multi-Ring Dielectric Resonator Antenna

IEEE Antennas and Wireless Propagation Letters, 2019
A three-dimensional (3-D)-printed wideband multi-ring dielectric resonator antenna (DRA) is investigated for the first time. It consists of four concentric dielectric rings with decreasing effective dielectric constants in the radial direction.
