| Abstract: | The projective normality of smooth, linearly normal surfaces of degree 9 in  N is studied. All nonprojectively normal surfaces which are not scrolls over a curve are classified. Results on the projective normality of surface scrolls are also given. |
| Keywords: | surfaces embeddings projective normality adjunction theory |
