Monopole triangle over integers

Haochen Qiu, Fan Ye

We prove the surgery exact triangle for monopole (Seiberg--Witten) Floer homology over integer coefficients, extending the work of Kronheimer--Mrowka--Ozsváth--Szabó over $\mathb…

Orbit Braid Action on a Finite Generated Group

Haochen Qiu

This paper aims to generalize Artin's ideas to establish an one-to-one correspondence between the orbit braid group and a quotient of a group f…

Surgery formulas for Seiberg-Witten invariants and family Seiberg-Witten invariants

Haochen Qiu

We prove a surgery formula for the ordinary Seiberg-Witten invariants, and surgery formulas for the families Seiberg-Witten invariants of families of -manifolds obtained through…

Exotic diffeomorphisms on -manifolds with

Haochen Qiu

While the exotic diffeomorphisms turned out to be very rich, we know much less about the case, as parameterized gauge-theoretic invariants are not well defined. In this…

The Dehn twist on a connected sum of two homology tori

Haochen Qiu

Kronheimer-Mrowka shows that the Dehn twist along a -sphere in the neck of two surfaces is not smoothly isotopic to the identity. Their result requires that the manifolds a…

A surgery formula for Seiberg-Witten invariants

Haochen Qiu

We prove a surgery formula for the ordinary Seiberg-Witten invariants of smooth -manifolds with . Our formula expresses the Seiberg-Witten invariants of the manifold aft…
