Introduction to Simple Module

We start by describing the Brauer tree, a combinatorial object that encodes first the decomposition matrix of the block, then Ext1 between simple modules in the block, and indeed the Morita equivalence type of the block (but not the source algebra).

We prove the geometric $q$-character formula conjectured by Hernandez and Leclerc in types $\mathbb{A}$ and $\mathbb{B}$ for a class of simple modules called snake modules introduced by Mukhin and Young.

Then, we determine those simple modules that give rise to finite-dimensional Nichols algebras for the case $n=2$.

In this note, we prove that if $\Lambda$ is an Artin algebra with a simple module $S$ of finite projective dimension, then the finiteness of the finitistic dimension of $\Lambda$ implies that of $(1-e)\Lambda(1-e)$ where $e$ is the primitive idempotent supporting $S$.

We construct two functors which transform simple restricted modules with nonzero levels over the standard affine algebras into simple modules over the three-point affine algebras of genus zero.

Three basic simple modules allows to achieve complex models for a real mine.

In particular, we show the Heisenberg vertex operator algebra gives an example of when the level one Zhu algebra, and in fact all its higher level Zhu algebras, do not provide new indecomposable non simple modules for the vertex operator algebra beyond those detected by the level zero Zhu algebra.

The first section deals with defining characteristic representations, introducing highest weight modules, Weyl modules, and building up to the Lusztig conjecture, with a diversion into Ext1 between simple modules for the algebraic group and the finite group.

We also describe complete resolutions of the simple module over groups algebras of elementary abelian groups and quantum complete intersections.

EnglishThe paper is devoted to the study of graded-simple modules and gradings on simple modules over finite-dimensional simple Lie algebras.

We give, along the way, various characterizations of minimax modules, as well as a structural description of meager modules, which are defined as those that do not have the square of a simple module as subquotient.

We determine the dimension of every simple module for the algebra of the monoid of all relations on a finite set (i.

We prove the Kac-Wakimoto conjecture for the periplectic Lie superalgebra $\mathfrak{p}(n)$, stating that any simple module lying in a block of non-maximal atypicality has superdimension zero.

We give new improved bounds for the dominant dimension of Nakayama algebras and use those bounds to give a classification of Nakayama algebras with $n$ simple modules that are higher Auslander algebras with global dimension at least $n$.

In this paper, we investigate the block that has an abelian defect group of rank $2$ and its Brauer correspondent has only one simple module.

if and only if $${\text {Hom}}(M/Z(M), S) \ne 0$$Hom(M/Z(M),S)≠0 for each singular simple module S.

The notion of (semi)bricks, regarded as a generalization of (semi)simple modules, appeared in a paper of Ringel in 1976.

Thus, once a formula for the characters of the indecomposable tilting $G$-modules has been found, a formula for the simple modules has been also.

The approach is based on a combination of three simple modules: 1) flood frequency analysis (frequency and peak discharge), 2) estimation of inundation depth, and 3) damage and loss estimation.

We describe the formal characters of some Weyl modules for simply connected and semisimple algebraic groups of type Dl over an algebraically closed field of characteristic where h is the Coxeter number, in the terms of the formal characters of simple modules.

In previous work by the author, a class of finite-dimensional semisimple Hopf algebras was considered with respect to the question under what condition all but one isomorphism class of simple modules are one-dimensional.

We explain how this induces an isomorphism between the monoid of dominant monomials, used to parameterize simple modules, and a quotient of the monoid of rectangular semistandard Young tableaux.

Furthermore, these simple modules when restricted as modules over N = 1 superconformal algebras coincide with those modules constructed in Yang et al.

We establish the prescription for refined characters in higher rank minimal models from the dual $(A_{n-1},A_{m-1})$ theories in the large $m$ limit, and then provide evidence for Song's proposal to hold (at least) in some simple modules (including the vacuum module) at finite $m$.

We obtain a large family of simple modules that have a basis consisting of Gelfand–Tsetlin tableaux, the action of the Lie algebra is given by the Gelfand–Tsetlin formulas and with all Gelfand–Tsetlin multiplicities equal 1.

The proposed CHB2 inverter incorporates individual PV elements into modules that can dynamically connect to their neighbors not only in series but also in parallel, which reduces conduction losses and enables simple module balancing.

As a result, simple modules for the Schrödinger algebra which are locally finite over the positive part are completely classified.

For all generic q ∈ ℂ*, when $$\mathfrak{g}$$ g is not of type A 1 , we prove that the quantum toroidal algebra $$U_q(\mathfrak{g}_{\rm{tor}})$$ U q ( g t o r ) has no nontrivial finite dimensional simple module.

The finite-dimensional simple modules over H and K, are classified; they all have dimension 1, respectively $$\le 2$$≤2.

Vertex operator algebras are especially well suited for studying logarithmic conformal field theory (in which correlation functions have logarithmic singularities arising from non-semisimple modules for the chiral algebra) because of the logarithmic tensor category theory of Huang, Lepowsky, and Zhang.

We establish a version of Ringel duality for this type of Lie superalgebras which allows to express the characters of tilting modules in terms of those of simple modules in that category.
