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 $3$ -folds. We fi…

On a theorem of Keller over a base ring

Zhihang Chen, Junwu Tu

Let $X$ be a quasi-compact separated scheme over a base field. Keller proved a theorem stating that the cyclic homology of $X$ is canonically isomorphic to the cyclic homology of t…

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…

Effective Categorical Enumerative Invariants

Andrei Caldararu, Junwu Tu

We introduce enumerative invariants $F_{g, n}$ $(g \geq 0$ , $n \geq 1)$ associated to a cyclic $A_{\infty}$ algebra and a splitting of its non-commutative Hodge filtration. These invari…

On the Morita invariance of Categorical Enumerative Invariants

Lino Amorim, Junwu Tu

Categorical Enumerative Invariants (CEI) are invariants associated with a unital, cyclic, smooth $A_{\infty}$ -category and a splitting of its non-commutative Hodge filtration. In thi…

Categorical enumerative invariants of the ground field

Junwu Tu

For an $S^{1}$ -framed modular operad $P$ , we introduce its "Feynman compactification" denoted by $F P$ which is a modular operad. Let ${M^{fr} (g, n)}_{(g, n)}$ be the $S^…
