Hi everybody,


Just a quick follow up on Dr. Hoffman's email on this week's events. In order to arrange food to be delivered for Wednesday's AWM lunch we would need a rough estimate of number of participants and dietary restrictions by this afternoon, so we can place the order in time. We would really appreciate if you RSVP today (to neil.r.hoffman@okstate.edu or alecost@okstate.edu). 



Wednesday 12:30 -1:30 Lunch and panel discussion with Jennifer Hom in MSCS 523 (all are welcome, but RSVP to neil.r.hoffman@okstate.edu with your dietary preferences and restrictions if you would like a lunch provided)  


Thursday 4:00-5:00 - Topology seminar in MSCS 514 - Speaker Jennifer Hom


Friday 3:30 -4:30 Distinguished Women in Mathematics Colloquium- MSCS 101 - Speaker Jennifer Hom (refreshments to follow)

Hello everyone,

The mathematics department will be hosting Jennifer Hom as our Distinguished Women in Mathematics Colloquium speaker. A full announcement on that will be sent out on Monday. In preparation for her visit, our own Jonathan Johnson will be giving a warm-up talk at 3:30 pm in MSCS 114 today: 

Title: Unknotting Numbers and Knot Floer Homology

Abstract: The unknotting number is a very natural and classical invariant of a knot. Despite this, this invariant is not well understood. For example, it is an open question how unknotting numbers behave under basic knot operations such as the connect sum and satellite operations. Floer homology has provide a suite of new invariants for 3-maifolds which has provided new techniques to study classical problems in knot theory. In preparation for next week's colloquium talk by Jennifer Hom, we will define knot Floer homology and discuss how it has been used to study unknotting numbers.


Events next week:
