Fiber products under toric flops and flips

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

Let $I^£$ and $I^£^{'}$ be two refinements of a fan $I^£_{0}$ and $f : X_{I^} £ ⇢ X_{I^£^{'}}$ be the birational map induced by $X_{I^} £ \to X_{I^£_{0}} \leftarrow X_{I^£^{'}}$ . W…

Quantum Extremal Transitions and Special L-values

Shuang-Yen Lee, Chin-Lung Wang, Sz-Sheng Wang

A threefold extremal transition $Y ↘ X$ consists of a crepant extremal contraction $I ¨ : Y \to Y ˉ$ with curve class $ℓ \in NE (Y)$ , followed by a sm…

Remarks on GW/PT under del Pezzo transitions

Shuang-Yen Lee, Chin-Lung Wang, Sz-Sheng Wang

A projective threefold transition $Y I ¨ Y ˉ ⇝ X$ is del Pezzo if $I ¨ $ contracts a smooth del Pezzo surface to a point. We show that the GW/PT corresp…
