29 p, 497.6 KB Non-existence of integral Hopf orders for twists of several simple groups of Lie type / Carnovale, Giovanna (Università degli Studi di Padova. Dipartimento di Matematica Tullio Levi-Civita) ; Cuadra, Juan (Universidad de Almería. Departamento de Matemáticas) ; Masut, Elisabetta (Università degli Studi di Padova. Dipartimento di Matematica Tullio Levi-Civita)
Let p be a prime number and q = pm, with m ≥ 1 if p 6= 2, 3 and m > 1 otherwise. Let Ω be any non-trivial twist for the complex group algebra of PSL2(q) arising from a 2-cocycle on an abelian subgroup of PSL2(q). [...]

31 p, 382.8 KB Integrability by separation of variables / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Ramírez, Rafael Orlando (Universitat Rovira i Virgili. Departament d'Enginyeria Informàtica i Matemàtiques)
We study the integrability in the Jacobi sense (integrability by separation of variables), of the Hamiltonian differential systems using the Levi-Civita Theorem. In particular we solve the Stark problem for N>3.

30 p, 450.5 KB Foliatons on porjective spaces associated to the affine lie algebra / da Costa, Raphael Constant (Universidad del Estado de Río de Janeiro)
In this work we construct some irreducible components of the space of two-dimensional holomorphic foliations on P n associated to some algebraic representations of the affine Lie algebra aff(C). We give a description of the generalized Kupka components, obtaining a classification of them in terms of the degree of the foliations, in both cases n = 3 and n = 4.

58 p, 677.7 KB Fine gradings on e6 / Draper Fontanals, Cristina (Escuela de las Ingenierías (Màlaga, Andalusia). Departamento de Matemática Aplicada) ; Viruel Arbáizar, Antonio (Universidad de Málaga. Departamento de Álgebra, Geometría y Topología)
There are fourteenfine gradings on the exceptional Lie algebra e6 over an algebraically closed field of zero characteristic. We provide their descriptions and a proof that any fine grading is equivalent to one of them.

36 p, 471.6 KB An inner automorphism is only an inner automorphism, but an inner endomorphism can be something strange / Bergman, George M.
The inner automorphisms of a group G can be characterized within the category of groups without reference to group elements: they are precisely those au-tomorphisms of G that can be extended, in a functorial manner, to all groups H given with homomorphisms G ! H: (Precise statement in x1. [...]

32 p, 265.0 KB S_4-symmetry on the Tits construction of exceptional Lie algebras and superalgebras / Elduque, Alberto (Universidad de Zaragoza. Departamento de Matemáticas) ; Okubo, Susumu (University of Rochester. Department of Physics and Astronomy)
The classical Tits construction provides models of the exceptional simple Lie algebras in terms of a unital composition algebra and a degree three simple Jordan algebra. A couple of actions of the symmetric group S4 on this construction are given. [...]

21 p, 221.2 KB Associative and Lie algebras of quotients / Perera Domènech, Francesc (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Siles Molina, Mercedes (Universidad de Málaga. Departamento de Álgebra, Geometría y Topología)
In this paper we examine how the notion of algebra of quotients for Lie algebras ties up with the corresponding well-known concept in the associative case. Specifically, we completely characterize when a Lie algebra Q is an algebra of quotients of a Lie algebra L in terms of the associative algebras generated by the adjoint operators of L and Q respectively. [...]
