| Research Abstract |
We have studied the structure of smooth projective 3-fold X with negative Kodaira dimension admitting non-isomorphic etale endomorphisms. The trouble is that there may exist KX-negative extremal rays which are not preserved by any power of f. However, by replacing f by a composite with a suitable automorphism of X, minimal model programs work in the category of etale edomorphisms in many cases. We have classified the candidate of such a variety X.
