Automorphism groups of rigid complete intersections
Jorge Duque Franco, Alvaro Liendo, Ana Julisa Palomino
We study the automorphism groups of complete intersections of hypersurfaces of strictly increasing degrees in projective space. Under a combinatorial rigidity condition on the tupl…

A one-step counterexample to the normalized Nash blowup conjecture
Alvaro Liendo, Ana Julisa Palomino, Gonzalo Rodríguez
We construct an explicit normal singular affine toric variety X of dimension five over an algebraically closed field of characteristic three such that the normalized Nash blowup of…

Automorphisms of prime power order of weighted hypersurfaces
Alvaro Liendo, Ana Julisa Palomino
We study automorphisms of quasi-smooth hypersurfaces in weighted projective spaces, extending classical results for smooth hypersurfaces in projective space to the weighted setting…
