## 5. Mirror theorem for a product of projective bundles

In this section, we construct a twisted *I*-function for a product of projective bundles each coming from a vector bundle. The proof is based on the proof of the mirror theorem for a projective bundle [21, Theorem 1.1]. This section is independent of the previous section. By combining Theorem 4.2 with the mirror theorem (Theorem 5.1), we will establish the main result in the next section.

**Remark 5.8.** For convenience, we list the rings to which the functions introduced in this section belong.
