XIX School on Differential Geometry

IMPA, Rio de Janeiro, July 18 – 22

Conference Venue

IMPA is located in the South Zone of Rio de Janeiro, near the Tijuca Forest and the Botanical Gardens, 20 minutes from major hotels of Leblon and Ipanema. You can find our address and some practical information about how to get to the institution below.

On leaving the airport we suggest that you take a taxi. There are several companies that have booths located inside the airport facilities, on the way out. A ride to South Zone costs around R$120 to R$150 and takes about 50 minutes. There are also special buses leaving from Terminals 1 and 2, whose routes you can find here
How to get to IMPA:

From the airport


There are three bus lines running near the Institute:

  • 409 – Saens Peña – Horto (via Lapa)
  • 416 – Saens Peña – Jardim Botânico (Horto) (via Túnel Rebouças)

You can check which buses line is the best for you by clicking here.

The passenger must pay as they enter, using the front door to get on the bus and the rear door to get off the bus. The bus fare is R$ 3,80 and the maximum change given is for a R$ 20,00 bill.

Should you prefer to use a taxi, we suggest the following companies:

Mini Course


Given the predictable limitations of support from funding agencies and the desire to have the largest possible number of participants, the committee strongly recommend the person to try to get funding for travel and per diem of their own home institutions.

Visa Information

The Brazilian visa system operates under a strict reciprocity policy. That means that all citizens from countries which require visas from Brazilians will have to obtain visas to attend the conference. Beware that to attend a scientific conference in Brazil a tourist visa suffices. Source: Consulate General of Brazil

Foreign participants should get in touch with the nearest Brazilian Consulate (click on the map) to find out whether a visa is required.
Here you find the list of nationalities that are exempt from this requirement, see also the official Ministry of Tourism page, that includes the whole of the European Union and Mercosur. Those who do need visa should note that a tourist visa suffices for the conference attendance; for more information about Brazil, visit the official Brazilian Institute of Tourism website.

In case you need an invitation letter, please contact us: dac@impa.br
