ON BIRATIONAL AUTOMORPHISMS OF RATIONAL SURFACES

Generators and relations of the groups of birational automorphisms are described for six classes of (-minimal) rational surfaces. For surfaces with , and , , relations between the already known generators are described, and for surfaces with , , and , , generators and relations are described.
