Gromov–witten Classes, Quantum Cohomology, and Enumerative Geometry
نویسندگان
چکیده
The paper is devoted to the mathematical aspects of topological quantum field theory and its applications to enumerative problems of algebraic geometry. In particular, it contains an axiomatic treatment of Gromov–Witten classes, and a discussion of their properties for Fano varieties. Cohomological Field Theories are defined, and it is proved that tree level theories are determined by their correlation functions. Application to counting rational curves on del Pezzo surfaces and projective spaces are given. §

Quantum cohomology of Grassmannians
The (small) quantum cohomology ring of a Grassmann variety encodes the enumerative geometry of rational curves in this variety. By using degeneracy loci formulas on quot schemes, Bertram has proved quantum Pieri and Giambelli formulas which give a complete description of the quantum cohomology ring. In this talk I will present elementary new proofs of these results which rely only on the defini...
متن کاملGromov-witten Theory Learning Seminar
Today, Jonathan spoke, delivering an overview of Gromov-Witten theory and how associativity of quantum cohomology leads to applications in enumerative geometry. Today we always work over C, and follow Fulton-Pandharipande’s notes [FP96]. Classically, if X is a nonsingular projective variety and β ∈ H2(X;Z), we want to know how many algebraic curves in X represent the class β. This relates to ve...
متن کاملThe Quantum Cohomology of Blow-ups of P and Enumerative Geometry
The enumerative geometry of curves in algebraic varieties has taken a new direction with the appearance of Gromov-Witten invariants and quantum cohomology. Gromov-Witten invariants originate in symplectic geometry and were first defined in terms of pseudo-holomorphic curves. In algebraic geometry, these invariants are defined using moduli spaces of stable maps. Let X be a nonsingular projective...
متن کاملTangential Quantum Cohomology of Arbitrary Order
A large chunk of the intersection theory of the moduli stacks of n-marked, genus 0 stable maps to a specified target variety X is encoded by the quantum cohomology ring of X. In particular, one can use the associativity of the ring structure to calculate Gromov-Witten invariants and, thus, in favorable circumstances, to calculate the number of rational curves in X passing through an appropriate...
متن کاملQuantum Kirwan Morphism and Gromov-witten Invariants of Quotients Ii
This is the second in a sequence of papers in which we construct a quantum version of the Kirwan map from the equivariant quantum cohomology QHG(X) of a smooth polarized complex projective variety X with the action of a connected complex reductive group G to the orbifold quantum cohomology QH(X//G) of its geometric invariant theory quotient X//G, and prove that it intertwines the genus zero gau...
