Quantum invariance under non-smooth toric flops of the simplest type
For a non-smooth toric flop of the simplest type, we provide the $\textit{quantum product formulas}$ and construct the $\textit{degree-preserving}$ quantum correspondence via $\textit{generalized}$ analytic continuation which is achieved through a $\textit{regularization}$ map. Moreover, the generating functions of Gromov--Witten invariants with ancestors are invariant for $\textit{all genera}$.
