The Coloquio Latinoamericano de Algebra series began in 1981. In its early years, until 1994, it was mainly a regional event that brought together mathematicians from Argentina and Chile, sometimes with the participation of invited professors from other countries. After a long pause, these meetings were resumed in 2001 at the University of Córdoba, in Argentina. Subsequent editions of the Coloquio were held in:

  • 2003: Cocoyoc, México
  • 2005: Colonia, Uruguay
  • 2007: Medellín, Colombia
  • 2009: São Pedro, Brazil
  • 2012: Pucón, Chile
  • 2014: Lima, Perú
  • 2016: Buenos Aires, Argentina
  • 2017: Quito, Ecuador
  • 2019: Mexico City, Mexico

After skipping 2021 because of the pandemic, we are delighted to announce the comeback of the meetings this year in Santiago.

From the Airport to Santiago

Santiago International Airport is located approximately 20 kilometres West of the city. There are 3 official transport options:

  • Official Taxi:

    The airport has introduced Vía Controlada system. A ground transportation desk is located inside the luggage claim area, where you can request a taxi without pre-booking. There are regular taxis (painted black & yellow) which run on a meter, or tourist taxis (painted blue) which charge a fixed rate according to the area of the city you are traveling to.

  • Transfer Service:

    These are minibuses that offer a shared taxi service. They drive you from the airport and drop you off at your hotel. This should be arranged within the airport. Two companies offer this service: Transvip y Delfos.

  • By Bus:

    These are shuttle buses that go from the airport to the city. Two companies offer this service: Turbus and Centropuerto. You can catch these buses immediately upon exiting the main airport terminal. During the day they run frequently. You pay the driver directly. Once you arrive in Santiago, you can get off the bus at a subway (Metro) station and take the subway to your final destination.

Public Transport

To use public transport, It is recommended to buy a prepaid card Bip. This card is used in subway and buses.

  • Subway (Metro de Santiago):

    Santiago's subway has five lines. The main line (1) runs modern trains along the central East-West axis Alameda - Providencia - Apoquindo serving the center as well as the newer business districts of Providencia and Las Condes. At Los Héroes, Baquedano and Tobalaba stops, you can change to one of the three lines connecting the southern parts of the city to the center. The fiths line is in the South. You can check the map on the website subway . Tickets cost between 610 and 720 pesos (about USD 0.95 - 1.10), depending on time of day, and include transfers. There is no timetable. But usually the metro runs every 2-3 minutes.

  • Buses:

    The urban buses are called “micros” and the city buses system is called “Transantiago”. There are mainline buses that are white and green that circulate across the big thoroughfares like Alameda, Av. Providencia, etc. and feeder buses (with different colors) that connect with the city's outskirts. The most important stops of the route are listed in the windowshield. In or the app Transantiagomaster, iTransantiago or Micros, you can look for the bus lines that you need for a specific route. Tickets cost between 640 and 720 pesos (about USD 0.95 - 1.15) and allow the transfer to other buses or the subway. The only way to pay is with the prepaid card Bip. It can be recharged in the metro station or specific selling points

  • Taxis:

    The regular taxis are black cars with their yellow roofs can be hailed anywhere. In Santiago, there is a base price of 300 pesos (USD 0.50) plus around 130 pesos for each 200 m driven (or per minute when waiting). The rates are posted on the windscreen; the meter has to be where you can see it. You can request a radiotaxi by phone. It is more safe and comfortable. Or you can use a mobile application as Safer Taxi or Easy Taxi. Also, you can use Uber and Cabify applications - the legality or illegality of these applications is not regulated even-.

Getting to San Joaquin Campus

The Facultad de Matematicas is located on San Joaquin Campus, one of the four campuses of the Pontificia Universidad Catolica. The address of the campus is Av. Vicuña Mackenna 4860, San Joaquin, Santiago. The campus is just in front of the Metro station San Joaquin on Line 5. During the morning from 6 to 9 am and the evening from 6 to 9 pm, Line 5 of the Metro operates 2 services and the trains don’t stop at each station. Only the red train stops at San Joaquin station - look out for the red lights on the train carriage before you get on the train.

It is safer to cross the footbridge to get to the campus rather than crossing the road. You will find a global map of San Joaquin Campus here. On this map the way to the Facultad de Matematicas from the Metro is printed in red.
