AbstractWe show that the proof of Luna's conjecture about the classification of
general wonderful G-varieties can be reduced to the analysis of finitely many
families of primitive cases. We work out all primitive cases arising with any
classical group G.Wonderful varieties of type B and C.

AbstractA spherical system is a combinatorial object, arising in the theory of
wonderful varieties, defined in terms of a root system. All spherical systems
can be obtained by means of some general combinatorial procedures (parabolic
induction, fiber product and projective fibration) from the so-called primitive
spherical systems. Here we report the list of all primitive spherical systems.Primitive spherical systems.
