Based on the work of this thesis I was able to submit three preprints: Non-Secant Defectivity via Osculating Projections; On non-secant defectivity of Segre-Veronese varieties; Spherical blow-ups of Grassmannians and Mori Dream Spaces. The present thesis has more examples and some proofs are more detailed than on the papers", "categories": [ "math.AG" ], "abstract": "In the first part of the thesis, we study a classical invariant of projective varieties, the secant defectivity. The second part is devoted to modern algebraic geometry, we study the birational geometry of blow-ups of Grassmannians at points.", "revisions": [ { "version": "v1", "updated": "2017-05-16T12:21:01.000Z" } ], "analyses": { "subjects": [ "14N05", "14N15", "14E05", "14L10", "14M15" ], "keywords": [ "birational geometry", "special varieties", "grassmannians", "secant defectivity", "second part" ], "tags": [ "dissertation" ], "note": { "typesetting": "TeX", "pages": 141, "language": "en", "license": "arXiv", "status": "editable" } } }
