Sha-rigidity of adjoint Chevalley groups of types , , , over commutative rings
Elena Bunina, Vazgen Kirakosyan, Rachel Treskunov
We prove that every locally inner (class-preserving) endomorphism of adjoint Chevalley groups and their elementary subgroups over commutative rings is inner for the root systems A1…

Regular bi-interpretability and finite axiomatizability of Chevalley groups
Elena Bunina, Pavel Gvozdevsky
In this paper we consider Chevalley groups over commutative rings with~, constructed by irreducible root systems of rank . We always suppose that for the systems $A_2, B_\el…
