Orthogonal involution on algebras of degree 16 and the Killing form of E8
Skip Garibaldi
We exploit various inclusions of algebraic groups to give a new construction of groups of type E8, determine the Killing forms of the resulting E8's, and define an invariant of cen…

Vanishing of trace forms in low characteristics
Skip Garibaldi, Alexander Premet
Every finite-dimensional representation of an algebraic group G gives a trace symmetric bilinear form on the Lie algebra of G. We give criteria in terms of root system data for the…

Orthogonal representations of twisted forms of SL2
Skip Garibaldi
For every absolutely irreducible orthogonal representation of a twisted form of SL2 over a field of characteristic zero, we compute the "unique" symmetric bilinear form that is inv…
