There is a relationship between higher algebra/category theory and differential topology. Evidence of this is abundant. For instance, Khovanov homology can be regarded as a knot invariant obtained from a suitable representation of a quantum group, the collection of which forms a braided monoidal category. Also, Turaev-Viro 3-manifold invariants are constructed from a suitably finite monoidal category. In the other direction, deformations of a point in an En-scheme over characteristic zero, such as a variety over the complex numbers, are indexed by framed n-manifolds. Hochschild (co)homology is an instance of this for n=1. This series will dwell on the foundations of this relationship. The talks will be framed by one main result, and a couple formal applications thereof. The main construction is factorization homology with coefficients in higher (enriched) categories. The body of the talks will focus on precise definitions, emphasizing the essential aspects that facilitate the coherent cancellations which support the main result.

How to get to IMPA:
From the airport
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$150 and takes about 50 minutes. There are also special buses leaving from Terminals 1 and 2, whose routes you can find here.
There are three bus lines running near the Institute:
- 409 – Saens Peña – Horto (via Lapa)
- 416 – Saens Peña – Jardim Botânico (Horto) (via Túnel Rebouças)
You can check which buses line is the best for you by clicking here.
The passenger must pay as they enter, using the front door to get on the bus and the rear door to get off the bus. The bus fare is R$ 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:

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.
