Workshop on First-Passage Percolation

Cabo Frio, Rio de Janeiro, from 11/17 to 11/22

Over the past half century, the study of spatial growth models such as first-passage percolation has led to a rigorous theory for subadditive ergodic processes and far reaching predictions of KPZ theory. However, despite the prominent recent development within the field, there are many fundamental questions left unanswered. The objective of this workshop is to unite experienced researchers with young talents to discuss the recent developments within the field and challenges of the future. We hope that this workshop will incentive a new generation of probabilists to invest in the field, and together meet the challenges that awaits.

Topics to be treated: The asymptotic shape; competing growth and existence of geodesics; fluctuations and the existence of scaling exponents; columnar defects.

As an introduction to the current state of first-passage percolation, there will be a mini-course held at IMPA the week preceding the workshop (November 10-14), which the participants are welcome to attend. The workshop is part of a longer thematic programme on Probability Theory and Rigorous Statistical Mechanics, organized at IMPA. Participants of the workshop are encouraged to combine their participation with a stay at IMPA during this programme. A list of related events is found below.

Visa Information

I wish to remind that US and Mexican citizens must apply for a visa to come to Brazil, concerning Europeans citizens it depends of the country, so please get in touch with the nearest Brazilian Consulate in your country in this direction.

A natural question would be the type of visa you need. Since you will not be receiving income or employment in Brazil, a tourist visa is just fine.

In order to avoid bureaucracy delays, I advise you to apply for the tourist visa as soon as possible.

Please let me know if you need an official letter of invitation sending an e-mail

Organizers: Daniel Ahlberg and Vladas Sidoravicius
