摘要:
Let X subset of P-N be a smooth complex complete intersection such that omega X similar or equal to O-X (- 1). Let f : S -> X be a generically finite morphism from a smooth projective variety to X. Under some positivity assumption on the anticanonical divisor of S, if 2 <= dim S <= dim X - 2 we prove that the deformations of f are contained in a subvariety of codimension at least 2.
