Quantum invariance under non-smooth toric flops of the simplest type

Tsung-Chen Chen, Jia-Hua Chong, Hui-Wen Lin

For a non-smooth toric flop of the simplest type, we provide the $quantum product formulas$ and construct the $degree-preserving$ quantum correspondence via $\tex…

Fiber products under toric flops and flips

Tsung-Chen Chen, Hui-Wen Lin, Sz-Sheng Wang

Let $Σ$ and $Σ^{'}$ be two refinements of a fan $Σ_{0}$ and $f : X_{Σ} ⇢ X_{Σ^{'}}$ be the birational map induced by $X_{Σ} \to X_{Σ_{0}} \leftarrow X_{Σ^{'}}$ . We show t…
