The meeting will start on the morning of Saturday the 26th and end the following afternoon. As is tradition, we will have a plenary talk at 17h00 on Friday the 25th, joint with the Johns Hopkins Category Theory seminar. Mike Shulman will give the plenary talk on the theme of internal languages: “The science of notation: an invitation to internal languages”.

Travel and Accommodation Information
We will be competing with “Parent's Weekend” at JHU for hotel space, so attendees are urged to arrange accommodation as soon as proves convenient. Below we have some suggestions for hotels near to the Homewood Campus, or easily accessible via public or hotel transport.
- The nearest hotel, within walking distance to the campus, is the Inn at the Colonade where rooms run about ~$130.
- In Mount Vernon there are several options from which one can take the free Purple Circulator bus to 33rd street, including but not limited to: Hotel Revival, The Ivy Baltimore, Hotel Indigo, and the HI Baltimore (hostel)
- The Hotel RL Baltimore Inner Harbor is further away, but still on the Purple Circulator route.
- In the downtown area there are a few other hotels, such as the Embassy Suites.
- For more hotel suggestions, Johns Hopkins maintains a list of hotels, found here.
Although there are several airports in surrounding areas, we urge those flying to use Baltimore Washington International as it is the closest and is a short train-journey away from the city. In particular the MARC train runs between the airport and Penn. station, and the Purple Circulator stops at the station.
Parking in official lots is possible, and information about this is available on the JHU visitor parking page. There is a flat 9$/day fee for weekend parking in the South Garage and San Martin Garage
“Registration”
Although registration is optional, we do encourage those wishing to attend to send an email to ctoctoberfest19@math.jhu.edu with subject “Registration” so that we can obtain an approximate headcount. There is no deadline for registration.
Talk submission is now closed.
