Speaker: Jim Fowler (OSU)

Abstract: Manifolds are spaces which are locally modeled on Euclidean space, but might be globally twisted in some way; two-dimensional examples include a sphere or a torus.  If you've never seen manifolds before, no need to fear: we'll play with some first examples.  Then we'll sketch the machinery of  "piecewise-linear (PL) topology."

Armed with that machinery, a technique called "sunny collapse" will show that a three-dimensional sphere can be unknotted inside a six-dimensional sphere.
