Representability In Lambda Algebras [PDF]

open access: yesIndagationes Mathematicae (Proceedings), 1976
Summary§ 1 is concerned with the term model of the α-calculus. It is proved that Church's δ is not dofinable and that the definable functions into the numerals are constant. In § 2 it is proved that for several α-algebras the range of a representable function is either a singleton or infinite.

q-deformation of corner vertex operator algebras by Miura transformation

open access: yesJournal of High Energy Physics, 2021
Recently, Gaiotto and Rapcak proposed a generalization of W N algebra by considering the symmetry at the corner of the brane intersection (corner vertex operator algebra).

BPS states meet generalized cohomology

open access: yesJournal of High Energy Physics, 2023
In this note we review a construction of a BPS Hilbert space in an effective supersymmetric quiver theory with 4 supercharges. We argue abstractly that this space contains elements of an equivariant generalized cohomology theory E G ∗ − $$ {E}_G^{\ast ...

The model method: Crown jewel in Singapore mathematics

open access: yesAsian Journal for Mathematics Education, 2022
The model method is synonymous with Singapore Mathematics. The spiral structure of the mathematics curriculum, with its focus on problem solving, and the concrete-pictorial-abstract approach to teaching, supports the use of the model method to solve ...

REPRESENTATIONS OF REFLECTION ALGEBRAS [PDF]

open access: yesReviews in Mathematical Physics, 2002
We study a class of algebras B(n,l) associated with integrable models with boundaries. These algebras can be identified with coideal subalgebras in the Yangian for gl(n). We construct an analog of the quantum determinant and show that its coefficients generate the center of B(n,l).

Gelfand Models for Diagram Algebras [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
A Gelfand model for a semisimple algebra $\mathsf{A}$ over $\mathbb{C}$ is a complex linear representation that contains each irreducible representation of $\mathsf{A}$ with multiplicity exactly one.

Hamiltonian Quantization of Chern-Simons theory with SL(2,C) Group [PDF]

open access: yes, 2002
We analyze the hamiltonian quantization of Chern-Simons theory associated to the universal covering of the Lorentz group SO(3,1). The algebra of observables is generated by finite dimensional spin networks drawn on a punctured topological surface.

n -representation infinite algebras

open access: yesAdvances in Mathematics, 2014
From the viewpoint of higher dimensional Auslander-Reiten theory, we introduce a new class of finite dimensional algebras of global dimension n, which we call n-representation infinite. They are a certain analog of representation infinite hereditary algebras, and we study three important classes of modules: n-preprojective, n-preinjective and n-regular

On special covariants in the exterior algebra of a simple Lie algebra [PDF]

open access: yes, 2014
We study the subspace of the exterior algebra of a simple complex Lie algebra linearly spanned by the copies of the little adjoint representation or, in the case of the Lie algebra of traceless matrices, by the copies of the n-th symmetric power of the ...

Unbounded representations of ∗-algebras [PDF]

open access: yesPacific Journal of Mathematics, 1977
Basic results on unbounded operator algebras are given, a general class of representatio ns, called adjointable representations is introduced and irreducibility of representations is considered. A characterizati on of self-adjointness for closed, strongly cyclic ^-representations is presented.
