Automorphisms of wonderful varieties
Guido Pezzini
Let G be a complex semisimple linear algebraic group, and X a wonderful G-variety. We determine the connected automorphism group of X and we calculate Luna's invariants of X under…

Simple Immersions of Wonderful Varieties
Guido Pezzini
Let G be a semisimple connected linear algebraic group over C, and X a wonderful G-variety. We study the possibility of realizing X as a closed subvariety of the projective space o…

Wonderful varieties of type D
Paolo Bravi, Guido Pezzini
Let G be a complex connected semisimple group, whose simple components have type A or D. We prove that wonderful G-varieties are classified by means of combinatorial objects called…
