Abstract:
We classify up to conjugacy all subgroups of certain types in the full,
affine and special affine Cremona groups and prove that the
normalizers of these subgroups are algebraic. As an application, we
obtain new results on the linearization problem by generalizing
Białynicki-Birula's results of 1966–67 to disconnected groups. We prove
fusion theorems for $n$-dimensional tori in the affine and special affine
Cremona groups of rank $n$, and introduce and discuss the notions of Jordan
decomposition and torsion primes for the Cremona groups.
Keywords:
Cremona group, affine Cremona group, algebraic torus,
diagonalizable algebraic group, conjugate subgroups,
fusion theorems, torsion primes.
