Explore the fascinating world of links, knots, and their higher-dimensional counterparts in this illuminating lecture. Delve into the geometric descriptions of "classical" invariants under ambient isotopy for both traditional and higher-dimensional links. Gain insights through simple examples showcasing non-trivial values of these invariants. Learn from Pavel Putrov of ICTP as he guides you through the fundamental concepts and their applications in this hour-long exploration of topological structures.
