Fiber products under toric flops and flips
Tsung-Chen Chen, Hui-Wen Lin, Sz-Sheng Wang
Let and be two refinements of a fan and be the birational map induced by . We show t…
Gromov--Witten/Pandharipande--Thomas correspondence via conifold transitions
Yinbang Lin, Sz-Sheng Wang
Given a (projective) conifold transition of smooth projective threefolds from to , we show that if the Gromov--Witten/Pandharipande--Thomas descendent correspondence holds f…
The movable cone of Calabi--Yau threefolds in ruled Fano manifolds
Atsushi Ito, Ching-Jui Lai, Sz-Sheng Wang
We describe explicitly the chamber structure of the movable cone for a general complete intersection Calabi--Yau threefold in a non-split -dimensional -rul…
A remark on deformations of -convex manifolds with exceptional curves
Sz-Sheng Wang
A formula for the dimension of the smoothing component of a -dimensional isolated Cohen--Macaulay singularity is shown. We apply this formula for a -convex threefold with a c…
Decorated sheaves and morphisms in tilted hearts
Yinbang Lin, Sz-Sheng Wang, Bingyu Xia
We identify limit stable pairs and stable framed sheaves as epimorphisms and monomorphisms, respectively, in tilts of the standard heart, under suitable conditions. We then identif…
The movable cone of certain Calabi-Yau threefolds of Picard number two
Ching-Jui Lai, Sz-Sheng Wang
We describe explicitly the chamber structure of the movable cone for a general smooth complete intersection Calabi-Yau threefold of Picard number two in certain Pr-ruled Fano m…
A note on nodal determinantal hypersurfaces
Sz-Sheng Wang
We prove that a general determinantal hypersurface of dimension 3 is nodal. Moreover, in terms of Chern classes associated with bundle morphisms, we derive a formula for the inters…
On the connectedness of the standard web of Calabi-Yau 3-folds and small transitions
Sz-Sheng Wang
We supply a detailed proof of the result by P.S. Green and T. Hbsch that all complete intersection Calabi--Yau 3-folds in product of projective spaces are connecte…
Extensions of multiply twisted pluri-canonical forms
Chen-Yu Chi, Chin-Lung Wang, Sz-Sheng Wang
Given a projective variety X, a smooth divisor D, and semipositive line bundles (L_1,h_1),,...,(L_m,h_m), we consider the "multiply twisted pluricanonical bundle" F:=m(K_X+D)+L_1+.…
