Automorphisms of toric varieties and Gale duality
Ivan Arzhantsev, Kirill Shakhmatov
We classify complete toric threefolds such that the automorphism group acts on with an open orbit whose complement does not contain a divisor. The latter co…

Infinite transitivity and polynomial vector fields
Rafael B. Andrist, Ivan Arzhantsev
We prove that for many pairs of root subgroups of the automorphism group the diagonal action of the group generated by on $(\mathbb…

Elements of finite order in the normalizer of a maximal torus of a semisimple group
Ivan Arzhantsev, Alexey Galt, Alexey Staroletov
We prove that the set of elements of a given finite order in the connected component of the normalizer of a maximal torus of a semisimple group is either emp…
