Directions
Map of Montreal
DownTown.
To McGill University:
805 Sherbrooke Str. West. The univeristy downtown campus is on Sherbrooke
street (one of the main streets of downtown going EastWest). The math
department is in Burnside Hall, which is the tall building to your right
when you stand on Sherbrooke str. facing the campus. The lecture room is
on the 9th floor, the secretaries' on the 10th, and the library
on the 11th. From the Chateau Versailles of from the Monfort, you
have to go on Sherbrooke, heading east (or take bus 24 on Sherbrooke).
It is a 15 minutes walk (even in a snow blizzard).
To Concordia University:
1455 Maisoneuve West. There are two buildings. The math dept is on
the southern one (also called the Library building). The lecture room is
on the 5th floor, and CICMA offices are on the 6th floor. The Library
is on the 2nd floor, accessible by stairs from the ground floor only.
To the Math. Dept. U. Vermont, Burlington:
The math dept address is 16 Colchester ave. Here is a link
(or here) to the dept.
website. The lecture room itself in on the ground floor of the building.
Coming on Hwy 89, take Exit 14 West which is Main Street. You drive (heading
west) on Main street heading towards the University of Vermont Lake Champlain.
Turn right on South Prospect Street and immediately left to College Street
and park at the Visitors parking. To get to the math dept continue on South
Prospect Street heading North (!), turn right on Pearl Street (note that
``Pearl Street"= ``Colchester Ave.", the former west of Prospect, the latter
East of Prospect) . The deparment of Math would be one of the next buildings
on your left. You would recognize it from the picture.
