Title: Weighted blowup correspondence of orbifold Gromov--Witten invariants and applications,
Abstract: Let $\sf X$ be a symplectic orbifold groupoid with $\sf S$ being a symplectic
sub-orbifold groupoid, and $\sf X_{\mathfrak a}$ be the weight-$\mathfrak a$
blowup of $\sf X$ along $\sf S$ with $\sf Z$ being the corresponding
exceptional divisor. We show that there is a weighted blowup correspondence
between some certain absolute orbifold Gromov--Witten invariants of $\sf X$
relative to $\sf S$ and some certain relative orbifold Gromov--Witten
invariants of the pair $(\sf X_{\mathfrak a}|Z)$. As an application, we prove
that the symplectic uniruledness of symplectic orbifold groupoids is a weighted
blowup invariant.
