| Summary |
This paper studies the adjunction theory of smooth 3-folds in [double-struck capital]P⁵. Because of the many special restriction on such 3-folds the structure of the adjunction theoretic reductions are especially simple, e.g., the 3-fold equals its first reduction, the second reduction is smooth except possibly for a few explicit low degrees, and the formulae relating the projective invariants of the given 3-fold with the invariants of its second reduction are very explicit. Tables summarizing the classification of such 3-folds up degree 12 are included |
