B-model Categorical Enumerative Invariants and holomorphic anomaly equations
Yefeng Shen, Junwu Tu
In this paper, we study the B-model categorical enumerative invariants (CEI) associated with derived categories of coherent sheaves on smooth projective Calabi-Yau -folds. We fi…
On a theorem of Keller over a base ring
Zhihang Chen, Junwu Tu
Let be a quasi-compact separated scheme over a base field. Keller proved a theorem stating that the cyclic homology of is canonically isomorphic to the cyclic homology of t…
On the Morita invariance of Categorical Enumerative Invariants
Lino Amorim, Junwu Tu
Categorical Enumerative Invariants (CEI) are invariants associated with a unital, cyclic, smooth -category and a splitting of its non-commutative Hodge filtration. In thi…
A remark on the B-model Comparison of Hodge structures
Junwu Tu
In this note we record a comparison theorem on the B-model variation of semi-infinite Hodge structures. This result is considered a folklore theorem by experts in the field. We onl…
