Alternating knot with unknotting number one

The unknotting number is a classical knot invariant which is easy to define but generally hard to compute. It is now known that an alternating knot has unknotting number one if and only if it has an unknotting crossing in every alternating diagram. This talk will explain the main ideas behind the proof of this fact.
