The homology of groupnets [PDF]
In this thesis I use the theory of groupnets (Brandt groupoids) to investigate the homology of mapping cylinder groupnets; that is, groupnets G which are the homotopy colimits of diagrams (V, A) of groupnets.

The dual of z-submodules of modules and some of extensions
Let R be a commutative ring with identity and M be an R-module. The purpose of this paper is to introduced the dual notion of z-submodules of M and some of extensions.

The universal enveloping algebra $U(\mathfrak{sl}_2)$ of $\mathfrak{sl}_2$ is a unital associative algebra over $\mathbb C$ generated by $E,F,H$ subject to the relations \begin{align*} [H,E]=2E, \qquad [H,F]=-2F, \qquad [E,F]=H. \end{align*} The element $

COMODULES OVER WEAK MULTIPLIER BIALGEBRAS
This is a sequel paper of [2] in which we study the comodules over a reg- ular weak multiplier bialgebra over a field, with a full comultiplication. Replacing the usual notion of coassociative coaction over a (weak) bialgebra, a comodule is defined via a

Let R be a commutative ring with identity and M be an R-module. A non-zero submodule N of M is said to be a weakly second submodule if rsN⊆K, where r,s∈R and K is a submodule of M, implies either rN⊆K or sN⊆K.

Produced representations of Lie algebras and Harish-Chandra modules
The comultiplication of the universal enveloping algebra of a Lie algebra is used to give modules produced from a subalgebra, an additional compatible structure of a module over an algebra of formal power series. When only the k \

Rational Cherednik algebras, quiver Schur algebras and cohomological Hall algebras [PDF]
This thesis is devoted to three interrelated problems in representation theory. The first problem concerns the combinatorial aspects of the connection between rational Cherednik algebras at $t=0$ and Hilbert schemes.

ON ENDOMORPHISMS OF MULTIPLICATION AND COMULTIPLICATION MODULES
. Let R be a ring with an identity (not necessarily commutative) and let M be a left R-module. This paper deals with multiplication and comultiplication left R-modules M having right EndR(M)-module structures ...

Coalgèbres d'Alexander-Whitney : un modèle algébrique pour les espaces topologiques [PDF]
The goal of this work is to study Alexander-Whitney coalgebras (first defined in [HPST06]) from a topological point of view. An Alexander-Whitney coalgebra is a coassociative chain coalgebra over Z with an extra algebraic structure : the comultiplication
