## 2. Genus-zero Gromov-Witten theory

In this section, we briefly recall the (torus-equivariant/twisted) genus-zero Gromov-Witten theory. We will introduce Gromov-Witten invariants, Givental Lagrangian cones and the quantum Riemann-Roch theorem.

2.1. **Gromov-Witten invariant and its variants**. We recall the definition of Gromov-Witten invariant. We also introduce an torus-equivariant version and a twisted version of it.

2.3. **Quantum Riemann-Roch theorem and twisted theory.** We introduce quantum Riemann-Roch theorem [9, Corollary 4], which relates twisted Givental cones via some transcendental operators. We also explain relationships between the Gromow-Witten theory of a vector bundle (resp. a subvariety) and that of a base space (resp. an ambient space) in terms of twisted theories. Note that we will use the material in this subsection only in Section 5.
