Abstract: In four dimensions it is possible to have a pair of smooth surfaces that are something known as topologically isotopic (intuitively one can deform one to another without ripping) but not smoothly equivalent (any map taking one to the other would have to wrinkle things in a serious way.) This talk will explore the construction of such surfaces, demonstrating that such behavior is very common.
