Abstract: This talk has a simple thesis statement: torus surgeries are a powerful tool to study 4-manifolds, we apply this technology to knot traces. The key insight is that annulus twisting a knot's Dehn surgery can be realized 4-dimensionally as a torus surgery on the knot's trace. We will then sketch a few applications of this idea.
