Instantons, Suspension, and Surgery

Explore a conference talk delving into advanced topics in gauge theory and low-dimensional topology. Learn how the concept of "suspension" naturally emerges when associating relative invariants to manifolds with one boundary component and b^+(W) 0. Discover the process of proving an inequality for q_3(Y) when Y bounds a manifold W with H_1(W;Z) free of 2-torsion. Examine how this construction can be applied to study obstructed cobordism maps more generally. Gain insights into the continuation of Ali's discussion on instantons, suspension, and surgery in this hour-long presentation from the Gauge Theory and Low Dimensional Topology conference held at the University of Miami.
