Quasi self-dual codes over non-unital rings from three-class association schemes
Let $ E $ and $ I $ denote the two non-unital rings of order 4 in the notation of (Fine, 93) defined by generators and relations as $ E = \langle a, b \mid 2a = 2b = 0, a^2 = a, b^2 = b, ab = a, ba = b\rangle $ and $ I = \langle a, b \mid 2a = 2b = 0, a ...

Traces on Semigroup Rings and Leavitt Path Algebras [PDF]
The trace on matrix rings, along with the augmentation map and Kaplansky trace on group rings, are some of the many examples of linear functions on algebras that vanish on all commutators.

Tunable Delay Lines in Silicon Photonics: Coupled Resonators and Photonic Crystals, a Comparison
In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as tunable delay lines.

Branch rings, thinned rings, tree enveloping rings [PDF]
We develop the theory of ``branch algebras'', which are infinite-dimensional associative algebras that are isomorphic, up to taking subrings of finite codimension, to a matrix ring over themselves. The main examples come from groups acting on trees. In particular, for every field k we construct a k-algebra K which (1) is finitely generated and infinite-

Medieval jewelry at the “Palace Center – East” site in Pliska
This paper presents jewelry falling into two categories, divided by their material composition – a group of metal items, and a group made from glass. They were found during archaeological excavations of the “Palace Center – East” site in Pliska.

Unification Theories: Rings, Boolean Algebras and Yang–Baxter Systems
This paper continues a series of papers on unification constructions. After a short discussion on the Euler’s relation, we introduce a matrix version of the Euler’s relation, E I π+U=O.
