Rost invariant on the center, revisited
S. Garibaldi, A. S. Merkurjev
The Rost invariant of the Galois cohomology of a simple simply connected algebraic group over a field is defined regardless of the characteristic of , but unfortunately some…
The Rost invariant has trivial kernel for quasi-split groups of low rank
R. Skip Garibaldi
For G an almost simple simply connected algebraic group defined over a field F, Rost has shown that there exists a canonical map R_G: H^1(F, G) --> H^3(F, Q/Z(2)). This includes th…
Groups of type E_7 over arbitrary fields
R. Skip Garibaldi
Freudenthal triple systems come in two flavors, degenerate and nondegenerate. The best criterion for distinguishing between the two which is available in the literature is by desce…
Structurable algebras and groups of type E_6 and E_7
R. Skip Garibaldi
It is well-known that every algebraic group of type F_4 is the automorphism group of an exceptional Jordan algebra, and that up to isogeny all groups of type ^1E_6 with trivial Tit…
