Exemples de surfaces canoniques de ${\mathbb P}^6$ et de solides de Calabi-Yau de ${\mathbb P}^7$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/97536Using the global Gulliksen-Negård complex, we build in this note regular canonical surfaces of general type in ${\mathbb P}^6$, Calabi-Yau 3-folds in ${\mathbb P}^7$ and Fano anticanonical 4-folds, all of degree 17 and 20. We also give their Hodge number and syzygies.5 pages, in frenchAlgebraic Geometry14Jxx;14M07Exemples de surfaces canoniques de ${\mathbb P}^6$ et de solides de Calabi-Yau de ${\mathbb P}^7$text
