Universal Central Extension of Current Superalgebras
Representation as well as central extension are two of the most important concepts in the theory of Lie (super)algebras. Apart from the interest of mathematicians, the attention of physicist are also drawn to these two subjects because of the significant amount of their applications in Physics. In fact for physicists, the study of projective representations of Lie (super)algebras are very impo...
متن کاملOD-characterization of $U_3(9)$ and its group of automorphisms
Let $L = U_3(9)$ be the simple projective unitary group in dimension 3 over a field with 92 elements. In this article, we classify groups with the same order and degree pattern as an almost simple group related to $L$. Since $Aut(L)equiv Z_4$ hence almost simple groups related to $L$ are $L$, $L : 2$ or $L : 4$. In fact, we prove that $L$, $L : 2$ and $L : 4$ are OD-characterizable.

s printed May 21, 2011 Sanghoon Baek (UNIVERSITY OF OTTAWA) Essential dimension of simple algebras and its application to algebraic groups of type An In this talk, we introduce the notion of essential dimension of an algebraic structure and discuss some recent results on the essential dimension of certain classes of central simple algebras. We also relate these results to the essential dimensio...
متن کاملGeometric Properties of Neutral Signature Metrics on 4-dimensional Nilpotent Lie Groups
The classification of left invariant metrics of neutral signature on the 4-dimensional nilpotent Lie groups is presented. Their geometry is extensively studied with special emphasis on the holonomy groups and projective equivalence. Additionally, we focus our attention on the Walker metrics. They appear as the underlying structure of metrics on the nilpotent Lie groups with degenerate center. F...
