A knot theorists approach to singularities and their deformations

After a brief introduction to plane curve singularities, we recast some of their classical invariants in terms of modern knot theory. Then we will see connections between purely algebraic questions about deformations of singularities and purely knot theoretic questions about cobordisms between knots, and answer some of them. This talk aims to be elementary and will not assume familiarity with knot theory or singularity theory.
