Effect Algebras of Positive Self-adjoint Operators Densely Defined on Hilbert Spaces

Acta Polytechnica, 2011
We show that (generalized) effect algebras may be suitable very simple and natural algebraic structures for sets of (unbounded) positive self-adjoint linear operators densely defined on an infinite-dimensional complex Hilbert space.

A Novel Scheme for Construction of S-Box Using Action of Power Associative Loop and Its Applications in Text Encryption

IEEE Access
Substitution boxes (S-boxes) play an important role in symmetric key cryptography because they add complexity and resist cryptanalysis, improving the overall security of encrypted data.

Order preserving limits of finite-dimensional nest algebras. [PDF]

, 2002
We introduce order conserving embeddings as a more general form of order preserving embeddings between finite dimensional nest algebras. The structure of these embeddings is determined, in terms of order indecomposable decompositions, and they are shown ...

Orthosymplectic quotient quiver subtraction. Part II. Framed quivers

Journal of High Energy Physics
The technique of orthosymplectic quotient quiver subtraction is introduced for framed orthosymplectic quivers. This involves subtracting an orthosymplectic quotient quiver from a framed orthosymplectic 3d N $$ \mathcal{N} $$ = 4 quiver gauge theory which

Lie algebras: infinite generalizations and deformations [PDF]

, 1990
There are many applications of Lie algebras to theoretical physics. This thesis is a study of some new mathematical structures which also are applicable to current physical ideas.

No-cycle algebras and representation theory [PDF]

In the first half of this dissertation we study certain quotient algebras of preprojective algebras called no-cycle algebras N. These are studied via one-cycle algebras, which are introduced here.

Invariant algebras and completely reducible representations [PDF]

, 1994
We give a general construction of affine noetherian algebras with the property that every finite dimensional representation is completely reducible. Starting from enveloping algebras of semi simple Lie algebras in characteristic zero we obtain explicit ...

Two Generator Subalgebras Of Lie Algebras. [PDF]

, 2007
In [14] Thompson showed that a finite group G is solvable if and only if every twogenerated subgroup is solvable (Corollary 2, p. 388). Recently, Grunevald et al.

Code CFTs and topological matter

Journal of High Energy Physics
In this paper, we propose a novel framework for modeling topological phases of matter using code-based Narain conformal field theories (NCFTs). We show that the algebraic structure of the NCFTs naturally embeds into critical lattice quantum field theory,
