Is, a larger hopf algebra built from the same principles, but leaving enough room to also like to thank the contributors of the mupad project, and especially those of the combinat package, for providing the development environment for this research (see [14] for an introduction. Algebra projects posted on october 10, 2010 by johan here is a list of algebra projects that i eventually want to have written up for the stacks project this list is a bit random, and i will edit it every now and then to add more items hopefully i’ll be able to take some off the list every now and then also introduction to hopf. Abstract algebra is the subject area of mathematics that studies algebraic structures, such as groups, rings, fields, modules, vector spaces, and algebrasthe phrase abstract algebra was coined at the turn of the 20th century to distinguish this area from what was normally referred to as algebra, the study of the rules for manipulating formulae and algebraic expressions involving unknowns and. Hopf algebras: motivations and examples questions and projects in hopf algebras we show that there is a hopf algebra structure associated with this problem which is, in a certain sense. Hopf algebras and invariants of the johnson cokernel jim conant, martin kassabov abstractwe show that if h is a cocommutative hopf algebra, then there is a natural action of aut(fn) on h n which induces an out(fn) action on a quotient h nin the case when h = t(v) is the tensor algebra, we show that the invariant trc of the cokernel of the johnson homomorphism studied in [5] projects to take.

Abstract: in this project we introduce the notion of algebras and coalgebras over a commutative ring, in order to define an algebraic structure called a hopf algebra we develop some (co)module-theory over these (co)algebras, and discuss the structure and duality between algebras and coalgebras. Hopf algebras have become ubiquitous in physics we cite here only a few examples: • feynman graphs are associated with an algebra related to the hopf algebra of rooted trees [4, 5] • in quantum statistical mechanics, the partition function description can be shown to give rise to a hopf algebra structure essentially a zero-dimensional. Which is an abstract form of the yang–baxter equationone denotes the hopf algebra structure by for the co-product, and denotes by the co-unit and by the antipode examples 1) when is an th root of , the quantum group is given by the polynomial algebra modulo (the group ring of ) with co-algebra, antipode and quasi-triangular structure.

In case a=d(h) is the drinfeld double of a finite dimensional hopf algebra h, our results implies the existence of a gerstenhaber bracket on h^_{gs}(h,h) this fact was conjectured by r taillefer in mathkt0207154. Theory provide a smooth transition from modern algebra to hopf algebras for example, the motivation for the definition of an exact sequence of hopf algebras project finally, i thank my wife, rebecca brower, my son, andre, and my parents. Quasi-doubled(h)for a finite dimensional cocommutative perfect weak hopf algebra project (no 19971074) supported by the national natural science foundation of china 1 in this paper, k always denotes a field.

On the drinfeld center of the category of comodules over a co-quasitriangular hopf algebra zhu, haixing, taiwanese journal of mathematics, 2016 hopf algebroids and galois extensions kadison, lars, bulletin of the belgian mathematical society - simon stevin, 2005. A braided hopf algebra in c is an algebra as well as coalgebra in c such that its comultiplication and counit are algebra morphisms, and such that the identity morphism id: r → r has a convolution inverse s in c. I want to learn more about hopf algebras but i am having trouble finding a down to earth introduction to the subject with lots of motivation and examples my algebra knowledge ranges from dummit and. Freeness of hopf algebras a thesis presented to the faculty of california state university, a hopf algebra as a module over a subhopfalgebra specifically he conjectured that “a insight on this project and throughout my studies at this university i would also like to. What are quantum groups ask question ok, a couple of months have passed since i posted this question, and i have begun this project on quantum groups i am now in the condition of answering a couple of the questions i posed $ which is always a hopf algebra the subject is interesting because it relates to the subject of quantum.

My research can best be classified with in the areas of representation theory (for example, of braided bialgebras, monoidal categories or 2-categories) and quantum algebra (hopf algebras, nichols algebras, etc) part of my recent work relates to categorification at roots of unity (joint work with vanessa miemietz and you qi. Serban raianu professional experience: professor, department chair - research project joint with the universities of antwerp, brussels, hasselt, all belgium, (participant) 1996-1999 35 the antipode of a dual quasi-hopf algebra with non-zero integrals is bijective. Department of mathematics and computer science, university of antwerp, ua, antwerp, belgium the bilateral project “hopf algebras in algebra, topology, geometry and physics” of the flemish and noetherian module algebras over a pointed hopf algebra saturday, june 1 0930-1020 d sternheimer and ph bonneau (univ de bourgogne). Quarks, leptons, and hopf algebra propagators received: 2/21/2011 / accepted: date abstract the weak quantum numbers of the elementary fermions arise as particular representations of the lie symmetry su(3) su(2) u(1) hopf algebras provide a generalization of lie algebras with the advantage that.

The purpose of the project is to identify the weak hopf quivers as the so called cayley graphs of the semigroups, especially of the clifford semigroups and give representation of the semilattice. 1 project description: geometric combinatorial hopf algebras: summary this proposal is about combinatorial algebra, with a geometrical avor together with students. We derive the universal r-matrix of the quantum-deformed enveloping algebra of centrally extended sl(2|2) using drinfeld's quantum double construction we are led to enlarging the algebra by additional generators corresponding to an sl(2) automorphism for this maximally extended algebra we construct a consistent hopf algebra structure where the extensions exhibit several uncommon features.

What is the significance of hopf algebras update cancel ad by the great courses plus the structure of a hopf algebra is exactly the structure an algebra [math]a[/math] needs in order to have natural [math]a project management is better when it's visual. His a hopf algebra, it is always graded commutative by the eckmann-hilton argument when it is also nitely generated (as it is known to be for many classes of hopf algebras discussed in section 2 below) one may use it to study representations of hgeometrically. Project level: honours, masters, phd the notion of a quasi hopf algebra dualises to that of a co-quasi hopf algebra which have so far received comparatively little attention.

Of a hopf algebra in [2], a quasi-bicrossed product is in a similar role for the quantum quasi- project supported by the national natural science foundation of china (no 19971074) and also by the natural science foundation of zhejiang province (no 102028) 306 li f. Abstract in an earlier paper, we proved that any triangular semisimple hopf algebra over an algebraically closed field k of characteristic 0 is obtained from the group algebra k[g] of a finite group g, by twisting its comultiplication by a twist in the sense of drinfeldin this paper, we generalize this result to not necessarily finite-dimensional cotriangular hopf algebras. A finite-dimensional hopf algebra h is called pointed if all simple h-modules are one-dimensional, where h is the dual hopf algebra of h most of the known examples of finite-dimensional non-semisimple hopf algebras are either pointed or have a pointed dual.
