Relative mirror symmetry for non-Fano varieties

Fenglong You

Given a smooth projective variety $X$ with a smooth anticanonical divisor $D$ , we study mirror symmetry for the log Calabi--Yau pair $(X, D)$ without assuming that $D$ is nef. We co…

Relative mirror symmetry, theta functions and the Gamma conjecture

Fenglong You

Let $X$ be a Fano variety, and $D \subset X$ be an snc anticanonical divisor. We study relative mirror symmetry for the log Calabi--Yau pair $(X, D)$ . (1) We prove a relative mirror…

Orbifold theta functions and mid-age invariants

Fenglong You

We use the orbifold approach to study theta functions in intrinsic mirror symmetry. We introduce a new type of orbifold invariants for snc pairs, called mid-age invariants, and use…
