SUMMARY:Josh Greene: \"Concordance Order and Three-Stranded Pretzel Knot
 s\"
DESCRIPTION:Abstract: I will talk about two recent approaches to the stu
 dy of smooth knot concordance\, one coming from Donaldson theory\, the o
 ther from Heegaard Floer homology.  Then I will discuss how to combine t
 he two to give an interesting test for a knot to be slice\, and apply th
 e test to determine the concordance order of three-stranded pretzel knot
 s.
