utomorphisms of Galois coverings of generic $m$-canonical projections Vik. S. Kulikov
Abstract: It will be shown that the Galois coverings induced by pluri-canonical generic coverings of projective spaces give, in dimensions one and two, serieses of specific actions of the symmetric groups $S_d$ on curves and surfaces not deformable to an action of $S_d$ which is not the full automorphism group.
