The regular representations of $\mathrm{GL} Poisson Methods for Isospectral Flows Deligne Categories and the Limit of Categories Rep(GL(m For classical Lie superalgebras of type I, we provide necessary and sufficient conditions for a Verma supermodule $Δ(λ)$ to be such that every non-zero homomorphism from another Verma supermodule to $Δ(λ)$ is injective. This is applied to describe the socle of the cokernel of an inclusion of Verma supermodules over the periplectic Lie superalgebras $\\mathfrak{pe}(n)$ and, furthermore, to ... 1.6. Our results can be illustrated as follows. The description of functors from Deligne categories to tensor categories looks like a category-theory version of the description of homomorphisms from a commutative ring to fields. Lie–Poisson systems and isospectral flows are two well-studied classes of dynamical systems. The former appear as Poisson reductions of Hamiltonian systems for which the configuration and symmetry space is a Lie group (see the monograph [] and references therein).The classical example is the free rigid body as viewed by Poincaré [].The latter, isospectral flows, appear as Lax formulations ... These formulas can be used to define a $\mathfrak{gl} (n)$-module structure on some infinite-dimensional modules - the so-called generic Gelfand-Tsetlin modules. The generic Gelfand-Tsetlin modules are convenient to work with since for every generic tableau there exists a unique irreducible generic Gelfand-Tsetlin module containing this tableau as a basis element. The regular representations of $\mathrm{GL}_{N}$ over finite local principal ideal rings Tsetlin modules of $\mathfrak{gl}(n ...

Note that for a sub-Lie group G G of the general linear group of order n n, the Lie algebra 𝔤 \mathfrak{g} is a subspace of the vector space of n × n n\times n matrices. It should be remarked that U ( n ) U(n) is a real subgroup of GL n ( ℂ ) GL_n(\mathbb{C}) but not a complex subgroup; hence its Lie algebra 𝔲 n \mathfrak{u}_n is a ... In mathematics, the Cartan decomposition is a decomposition of a semisimple Lie group or Lie algebra, which plays an important role in their structure theory and representation theory.It generalizes the polar decomposition or singular value decomposition of matrices. Its history can be traced to the 1880s work of Élie Cartan and Wilhelm Killing.

Suppose $\mathfrak{g}_0=\mathfrak{m}$ is the Levi subalgebra of a maximal parabolic lie algebra $\mathfrak{p}= \bigoplus_{n\geq 0}\mathfrak{g}_n$, where I am considering the grading induced by characters of the center of $\mathfrak{m}$. Quantum affine $\frak{gl} A Cartan subalgebra of gl n, the Lie algebra of n×n matrices over a field, is the algebra of all diagonal matrices.

General linear group of a vector space. If V is a vector space over the field F, the general linear group of V, written GL(V) or Aut(V), is the group of all automorphisms of V, i.e. the set of all bijective linear transformations V → V, together with functional composition as group operation.If V has finite dimension n, then GL(V) and GL(n, F) are isomorphic. The beautiful Beilinson-Lusztig-MacPherson construction [1] of quantum gl n has been generalised to the quantum affine gl n [4, 9], to the quantum super gl m|n [12], and partially to the other ...

Stack Exchange Network Stack Exchange network consists of 176 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Abstract. We will construct the Lusztig form for the quantum loop algebra of |$\mathfrak {gl}_{n}$| by proving the conjecture [4, 3.8.6] and establish partially the Schur–Weyl duality at the integral level in this case.We will also investigate the integral form of the modified quantum affine |$\mathfrak {gl}_{n}$| by introducing an affine stabilisation property and will lift the canonical ...
