摘要: where S*H°(I2) denote the symmetric algebra of H°(f2), is surjective. (2) The kernel I ~p generated by its elements degree 2 and 3. (3) except in following cases: (i) C a non-singular plane quintic (g= 6) (ii) trigonal (i.e., triple covering PI). (We refer reader to (4.11), (4.12) (4.13) for special study those exceptions).
