Dimension Reduction of Generalized ASD Instantons

Dylan Galt, Langte Ma

We study generalized anti-self-dual instantons defined over Riemannian manifolds equipped with a parallel codimension- $4$ differential form. In particular, for product Riemannian m…

Fiber Sum Formulae for the Casson-Seiberg-Witten Invariant of Integral Homology $S^{1} \times S^{3}$

Langte Ma

We prove the additivity of the Casson-Seiberg-Witten invariant of integral homology $S^{1} \times S^{3}$ under fiber sum along embedded curves and embedded tori, which is the $4$ -dimen…

A Surgery Formula for the Casson-Seiberg-Witten Invariant of Integral Homology $S^{1} \times S^{3}$

Langte Ma

We prove a surgery formula of the Casson-Seiberg-Witten invariant of integral homology $S^{1} \times S^{3}$ along an embedded torus, which could either be regarded as an extension of t…
