Open -spin theory in genus one, and the Gelfand-Dikii wave function
Ran J. Tessler, Yizhen Zhao
We construct the sector of the open -spin theory, that is, an open -spin theory on the moduli space of cylinders. This is the second construction of a open inters…

The point insertion technique and open -spin theories II: intersection theories in genus-zero
Ran J. Tessler, Yizhen Zhao
The papers [5, 3, 6, 19, 20] initiated the study of open -spin and open FJRW intersection theories, and related them to integrable hierarchies and mirror symmetry. This paper us…

The point insertion technique and open -spin theories I: moduli and orientation
Ran J. Tessler, Yizhen Zhao
The papers [3,1,4,10] constructed an intersection theory on the moduli space of -spin disks, and proved it satisfies mirror symmetry and relations with integrable hierarchies. T…
