 A structure theorem for complete intersections Bull. Korean Math. Soc. 2009 Vol. 46, No. 4, 657-671 https://doi.org/10.4134/BKMS.2009.46.4.657Printed July 1, 2009 Eun Jeong Choi, Oh-Jin Kang, and Hyoung J. Ko Yonsei University, University of Incheon, and Yonsei University Abstract : Buchsbaum and Eisenbud proved a structure theorem for Gorenstein ideals of grade 3. In this paper we derive a class of the perfect ideals from a class of the complete matrices. From this we give a structure theorem for complete intersections of grade $g> 3$. Keywords : complete intersection of grade $g$, structure theorem MSC numbers : 13C05, 13C14, 13C40, 14M10 Downloads: Full-text PDF
