Lens space surgeries, bandings of links, and DNA recombination

Abstract:Remarkably, aspects of molecular biology may be studied through low dimensional topology. In particular, we may interpret DNA recombination as particular types of transformations between knots and links which in turn may be analyzed through Dehn surgery on knots in 3-manifolds and corresponding 2-handle attachments to 4-manifolds. We'll focus on the middle ground demonstrating how the Montesinos trick relates these transformations between knots and links to Dehn surgery and then exhibit a conjectural classification of both biological and topological interest.
