On simply laced Lie algebras and their minuscule representations

J. Lurie[1]

(1) Princeton University, USA

In this paper we adapt a known construction for the simply laced, semisimple Lie algebras (over Z), and thereby obtain a very simple construction for all minuscule representations of those Lie algebras (again over Z). We apply these results to give explicit formulas for tensors invariant under the exceptional algebras $ E_6 $ and $ E_7 $.

Keywords: Exceptional algebras, minuscule representations
