We will see different methods of constructing 3-dimensional shapes (3-manifolds). Then we will look at the notion of equivalence i.e. when are two such objects the 'same'. One of the ways to construct new 3-Manifolds is by Dehn surgery. Colloquially, to perform Dehn surgery one removes a neighborhood of a knot and glues it back in in a twisted way. One can ask questions about how 'similar' are two manifolds with respect to Dehn surgery. I will talk about some conjectures around this topic and what tools can be used to solve this.
