Monoid Extensions, Relaxed Actions and Cohomology
In this thesis a particular class of monoid extensions are studied and characterized, the weakly Schreier split extensions. It is demonstrated that both Artin glueings of frames and λ-semidirect products of inverse semigroups are examples of these extensions. The characterization is given in terms …

MONOID RINGS AND STRONGLY TWO-GENERATED IDEALS
<p>This paper determines whether monoid rings with the two-generator property have the strong two-generator property. Dedekind domains have both the two-generator and strong two-generator properties. How common is this? Two cases are considered here: the zero-dimensional case and the …

Internal monoid actions in a cartesian closed category and higher-dimensional group automorphisms
… the corresponding Aut (X), where Mₙ is a monoid. Since the category of catⁿ-groups is equivalent to Catⁿ (Groups) and since the cartesian closed category Sets Mₙ of Mₙ-sets is much easier to handle than the cartesian closed category of n-fold categories, we shall work just with …

Algebraic structure of endomorphism monoids of finite graphs
… die Menge aller Endomorphismen von Graphen ein Monoid ist, konzentrieren wir uns auf die algebraischen Strukturen, wie regulär, vollständig regulär, orthodox oder Clifford Halbgruppen. Da die allgemeine Situation zu kompliziert ist, studieren wir die algebraische Struktur auf dem Monoid einiger …

Species and Hyperplane Arrangements
… dissertation has two leading characters: Hopf monoids in the category of species and the Tits algebra of a real hyperplane arrangement. The relation between these two comes from the work of Aguiar and Mahajan (2013), who showed that a (co)commutative Hopf monoid gives rise to a family of …

Homotopy Theory of Monoids and Group Completion
… and partial models for the homotopy theory of monoids and the derived functor of group completion. We show that there is a simplicial model structure on the category of reduced simplicial sets that is Quillen equivalent to the Quillen model structure of simplicial monoids. Using this Quillen …

Restriction Semigroups: Structure, Varieties and Presentations
… semigroups arise from partial transformation monoids and form a wider class than inverse semigroups. Firstly, we produce a presentation of the Szendrei expansion of a monoid, which is a left restriction monoid, using a similar approach to Exel's presentation for the Szendrei expansion of a …

Exploring the multiplicative structure of Z/nZ
… exclusively on its structure as a multiplicative monoid, when endowed with the multiplication only. To do this, our approach relies on the study of monoid homomorphisms. In particular, we investigate the homomorphisms between two prime power multiplicative modular monoids, aiming to understand …

Non-commutative Gröbner Bases and Applications
… Gröbner bases. Gröbner basis theory in free monoid rings was carefully revised and Gröbner bases were precisely characterized in great detail. For the computations of Gröbner bases, the Buchberger Procedure was formulated. Three methods, say interreduction on obstructions, Gebauer-Möller …

Goodwillie calculus and I
… of based spaces, this point of view leads to a monoidal model for the derivatives. Such structure induces operad and module structures for derivatives of monads and their modules, leading to a chain rule for higher derivatives. We also define a category through which n-excisive finitary functors …

The Structure of endomorphism monoids of strong semilattices of left simple semigroups
Endomorphismenmonoide sind schon lange von Interesse in der universellen Algebra und werden für die Untersuchung bestimmter Klassen von algebraischen Strukturen eingesetzt. Für jede Algebra ist die Menge der Endomorphismen abgeschlossen unter Komposition und bildet ein Monoid (das heißt, eine …

Algebraic exponentiation and internal homology in general categories
… defined with respect to an internal commutative monoid in symmetric monoidal closed abelian category. (ii) Right adjoints for the pullback functors between D. Bourns categories of points. We introduce and study them in the situations where the ordinary pullback functors between bundles do not …

Homological classification of monoids by projectivities of right acts
Die Darstellung von Monoiden durch Transformationen von Mengen, die zu Akten über Monoiden führt, ist die Basis dieser Dissertation. Eine große Anzahl von Ergebnissen über Akte über Monoiden beziehen sich auf Fragen der homologischen Klassifikation, in der Eigenschaften von Akten über einem Monoid …

Permutation Patterns, Reduced Decompositions with Few Repetitions and the Bruhat Order
… order for the symmetric group and the rook monoid which is a generalization of the symmetric group. Finally, motivated by coding theory, the concepts of displacement, additive stretch and multiplicative stretch of permutations are introduced. These concepts are then analyzed with respect to …

Descent Systems, Eulerian Polynomials and Toric Varieties
… comes naturally from the theory of algebraic monoids. Using effectively the cross section lattice of a reductive monoid and the combinatorics of simple polytopes, we obtain a recurrence formula for the Poincar e polynomial of X(J) in terms of the Eulerian polynomials. Furthermore, we compute …

Interactions of (co)monads in Agda
… We study monads and comonads on an arbitrary monoidal category, assuming properties such as symmetry only if needed. We do not assume any axioms from classical mathematics which are noncomputable or those which would be incompatible with univalence such as choice, LEM or K. Our formalization …

Hyperequational theory for partial algebras
… (2)We define the operator Chi^A_Ph where Ph is a monoid of regular partial hypersubstitutions.Using this concept, we define the concept of a Phyp_R(\tau )-solid strong regular variety of partial algebras and we prove that a PHyp_R(\tau )-solid strong regular variety satisfies four equivalent …

Admissible orders on quotients of the free associative algebra
… we look at actions of the multiplicative monoid generated by the set of transvections and diagonal matrices with non-negative entries on the set of equivalence classes of admissible arrays under order-isomorphism and we analyze the stabilizers and orbits of these actions.</p>
