The Fundamental Theorem for locally projective geometries

Algebraic Geometry 2023-07-31 v2

Abstract

We deal with generalizations of the Fundamental Theorem of Projective Geometry to other related geometries (of dimension 3\geq 3) and non bijective maps. We consider locally projective geometries and locally affino-projective geometries (which include the classical M\"obius, Laguerre and Minkowski geometries).

Comments

An omission in the main statements is corrected (the considered projective spaces have dimensions >2). The preliminary section is improved using a better notion of partial morphism. arXiv admin note: text overlap with arXiv:2204.10594
