Lifts of cycles in tropical hypersurfaces and the Gamma conjecture

Yuto Yamamoto

For a complex hypersurface of dimension $d \geq 1$ in a toric variety, we construct lifts of tropical $(p, q)$ -cycles with $p + q = d$ in the associated tropical hypersurface. The trop…

Toric degenerations of Calabi--Yau complete intersections and metric SYZ conjecture

Keita Goto, Yuto Yamamoto

We consider a toric degeneration $X$ of Calabi--Yau complete intersections of Batyrev--Borisov in the Gross--Siebert program. For the toric degeneration $X$ , we…

Non-archimedean SYZ fibrations via tropical contractions

Yuto Yamamoto

We consider a toric degeneration of Calabi--Yau complete intersections of Batyrev--Borisov in the Gross--Siebert program. The author showed in his previous work that there exists a…

Periods of tropical Calabi--Yau hypersurfaces

Yuto Yamamoto

We consider the residual B-model variation of Hodge structure of Iritani defined by a family of toric Calabi--Yau hypersurfaces over a punctured disk $D ∖ {0}$ . It is na…
