Birational geometry of exceptional sets in Manin’s conjecture Algebraic Geometry seminar University of Cambridge, May 2024, The space of rational curves and Manin’s conjecture In mathematics, birational geometry is a field of algebraic geometry in which the goal is to determine when two algebraic varieties are isomorphic outside lower-dimensional subsets. This amounts to studying mappings that are given by rational functions rather than polynomials; the map may fail to be defined … See more Rational maps A rational map from one variety (understood to be irreducible) $${\displaystyle X}$$ to another variety $${\displaystyle Y}$$, written as a dashed arrow X ⇢Y, is … See more Every algebraic variety is birational to a projective variety (Chow's lemma). So, for the purposes of birational classification, it is enough to work only with projective varieties, and this is usually the most convenient setting. Much deeper is See more A projective variety X is called minimal if the canonical bundle KX is nef. For X of dimension 2, it is enough to consider smooth varieties in this definition. In dimensions at least … See more Algebraic varieties differ widely in how many birational automorphisms they have. Every variety of general type is extremely rigid, in the sense … See more At first, it is not clear how to show that there are any algebraic varieties which are not rational. In order to prove this, some birational invariants of algebraic varieties are needed. A birational invariant is any kind of number, ring, etc which is the same, or … See more A variety is called uniruled if it is covered by rational curves. A uniruled variety does not have a minimal model, but there is a good substitute: Birkar, Cascini, Hacon, and McKernan showed that every uniruled variety over a field of characteristic zero is birational to a See more Birational geometry has found applications in other areas of geometry, but especially in traditional problems in algebraic geometry.
