Program Description The seventeenth East Coast Operator Algebra Symposium (ECOAS) will be held at The Ohio State University October 12-13, 2019. The ECOAS focuses on operator algebras (C* and von Neumann algebras) and non-commuative geometry, with applications to a wide array of disciplines, including ergodic theory, representation theory, and mathematical physics.

Registration will be open through September 15, 2019. Please fill out the following registration form. Accommodation There are many hotels near campus at which you can make a reservation, including: The Blackwell ($150/night) Springhill Suites on Olentangy River Rd When making a hotel reservation, say it is for the ECOAS conference at OSU to get a special rate. If you are unable to get the special rate, let one of the organizers know. There are also many more hotel options near by if one of these does not work. Because there is no OSU football game the weekend of October 12-13, it seems there are many events planned in the area. It is probably a good idea to book your hotel earlier rather than later. Organization For more information, please contact: Corey Jones Henri Moscovici David Penneys [penneys (dot) 2 (at) osu (dot) edu] Travel information There is some funding available for travel reimbursement. Please contact David Penneys about such funding. If arriving by car, you can park in either: Tuttle Garage: 2000 Tuttle Park Pl, Columbus, OH 43210. It is one block from Cockins Hall, where the conference will take place. Lane Garage: 2100 Neil Ave, Columbus, OH 43210. It is a bit further; use if Tuttle is closed for some reason. Take a ticket when you enter the garage. If you are a speaker or have contacted David Penneys about travel funding, he will have a parking pass for you, which is a sticker you can place on the ticket which will pay for your parking.
