Directions

From NYC, the best way to travel to Stony Brook is via the LIRR, Port Jefferson branch, getting off at the Stony Brook station. Use the "MTA TrainTime" app to find scheduled trips and buy tickets. Click here for a detailed guide.

To return to NYC via the LIRR, there are trains from Stony Brook at 4:18pm and 6:49pm.

If you are planning to drive, take the Long Island Expressway (LIE, I-495) eastbound to exit 62, and follow Nicolls Road (Route 97) north for 9 miles. The main entrance to the University is on the left. Metered parking near the venue is available. (Lot 7 or 12; map here.)

Titles and Abstracts

Siddhi Krishna: Unknot detection through the ages


Knot theory is a rich subject which ties together many areas, including topology, geometry, representation theory, and others. Knot invariants assign some auxiliary object (e.g. a surface, 3-manifold, 4-manifold, polynomial, vector space, group, etc) to a knot, such that the auxiliary object is independent of how the knot is presented. The simplest knot is called the unknot, and a foundational question within low-dimensional topology is "which knot invariants detect the unknot?" In this talk, I'll survey various answers to this question over the past 60 years, ranging from the algebraic, to the topological, to the computational. I will not assume any background in low-dimensional topology for this talk -- all are welcome! 


Linda Keen: Dynamics of some interesting families of complex analytic functions.


Reimbursement 

If you are planning to travel from NYC by public transport, you can claim travel reimbursement. Electronic or physical receipts are to be kept (a picture of a physical receipt is insufficient). If you are driving, you must submit your starting address (from here, we can estimate the reimbursement based on the current IRS mileage rate). You can also submit receipts or an EZ Pass log to claim reimbursement for tolls. Reimbursement forms will be provided to you at the beginning of the event. If you have any questions, please feel free to email Dylan at dylan.galt@stonybrook.edu
