Cubic forms on adjoint representations of exceptional groups
M. M. Atamanova, A. Yu. Luzgarev St. Petersburg State University, St. Petersburg, Russia
Abstract:
We construct cubic forms on adjoint representation of the Chevalley group of type $\mathsf E_7$, whose partial derivatives are linear combinations of equations on the orbit of the highest weight vector. In order to describe the forms we introduce new combinatorial notions related to maximal squares in root systems of exceptional types.
Key words and phrases:
Chevalley groups, exceptional groups, multilinear invariants, root systems.
