Makar-Limanov invariants of nonnormal affine toric varieties
Ilya Boldyrev
We prove the equality of the Makar-Limanov invariant and the modified Makar-Limanov invariant in the case of not necessary normal affine toric varieties. Also we give a combinatori…

Automorphisms of nonnormal toric varieties
Ilya Boldyrev, Sergey Gaifullin
In this paper we prove criteria for a nonnormal toric variety to be flexible, to be rigid and to be almost rigid. For rigid and almost rigid toric varieties we describe the automor…
