Valuation rings in finite-dimensional division algebras

Journal of Algebra, 1989
By a valuation ring in a division algebra \(D\) the authors understand a subring containing for each \(x\) in \(D\) either \(x\) or \(x^{-1}\). Let \(D\) be a division algebra of dimension \(n^ 2\) over its centre \(K\) and let \(B\) be a valuation ring in \(K\).

Even-order subgroups of finite-dimensional division rings

Journal of Algebra, 1977
Let K be a field. A finite group G is called K-adequate if there exists a K-division ring D (a finite-dimensional division algebra central over K) such that G is contained in D*, the multiplicative group of nonzero elements of D. Fein and Schacher have investigated the problem of determining for which fields K there exists a noncyclic group of odd ...

Creation of Low-Loss Dual-Ring Optical Filter via Temporal Coupled Mode Theory and Direct Binary Search Inverse Design

Photonics
We propose a dual-ring optical filter based on direct binary search inverse design. The proposed device comprises two cascaded rings in an add–drop configuration.
