The Picard group of algebras over an algebraically nonclosed field
AbstractLet k be a field that is not algebraically closed, and let A be a k-algebra, whose each maximal ideal has residue field k. We prove that each element of the Picard group of A is of finite order and give an optimal upper bound for its order.

ASSOCIATIVE NIL-ALGEBRAS OVER FINITE FIELDS [PDF]
We study the nilpotency degree of a relatively free finitely generated associative algebra with the identity xn = 0 over a finite field đœ with q elements. In the case of q â„ n the nilpotency degree is proven to be the same as in the case of an infinite field of the same characteristic.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and templateâassisted selfâassembly methods. Precise design strategies achieve directional emission, lowâthreshold lasing, and tunable photonic bandgaps.

Structure Theorems for Basic Algebras [PDF]
A basic finite dimensional algebra over an algebraically closed field $k$ is isomorphic to a quotient of a tensor algebra by an admissible ideal. The category of left modules over the algebra is isomorphic to the category of representations of a finite ...

Comma vertex and string field algebra [PDF]
We study the matter part of the algebra of open string fields using the 3-string vertex over the sliver state, which we call ``comma vertex''. By generalizing this comma vertex to the N-string overlap, we obtain a closed form of the Neumann coefficients ...

Enhancing the Efficiency of Polariton OLEDs in and Beyond the SingleâExcitation Subspace
Organic lightâemitting diodes (OLEDs) are transforming lighting with ecoâfriendly manufacturing and flexible applications. However, since 75 % of excited states (triplets) are nonâemissive, recent research has focused on triplet harvesting. This work proposes a predictive polaritonâbased model, exploring conditions for OLED enhancement and showing that

Rings with involution whose symmetric elements are central
In a ring R with involution whose symmetric elements S are central, the skew-symmetric elements K form a Lie algebra over the commutative ring S. The classification of such rings which are 2-torsion free is equivalent to the classification of Lie ...

Description of the automorphism groups of some Leibniz algebras
Let $L$ be an algebra over a field $F$ with the binary operations $+$ and $[,]$. Then $L$ is called a left Leibniz algebra if it satisfies the left Leibniz identity: $[[a,b],c]=[a,[b,c]]-[b,[a,c]]$ for all elements $a,b,c\in L$.

Free Malcev algebra of rank three
We find a basis of the free Malcev algebra on three free generators over a field of characteristic zero. The specialty and semiprimity of this algebra are proved.
