An Invariant of Simple Algebraic Groups
The Rost invariant associated with a simple simply connected algebraic group G is used to define an invariant of strongly inner forms of G. This invariant takes values in a quotient of H(k, Q/Z(2)). It is used to answer a question of Serre about groups of type E6 and to prove a generalization of Gille’s splitting criterion for groups of type E6 and E7. For G a semisimple (affine) algebraic grou...

متن کاملInvariant Tensors and Graphs
We describe a correspondence between GLn-invariant tensors and graphs. We then show how this correspondence accommodates various types of symmetries and orientations.
متن کاملInvariant Tensors and Cellular Categories
Let U be the quantised enveloping algebra associated to a Cartan matrix of finite type. Let W be the tensor product of a finite list of highest weight representations of U . Then EndU (W ) has a basis called the dual canonical basis and this gives an integral form for EndU (W ). We show that this integral form is cellular by using results due to Lusztig.
