Satellite event for the International Congress of Mathematicians 2018 co-organised by the Sociedade Brasileira de Lógica and DLMPST/IUHPST. Contributed Papers and ICM Short Communications. The Scientific & Organising Committee invited all researchers in mathematical logic to submit abstracts (you can find the full call for abstract submissions here). We also encouraged all participants of our satellite conference to submit an abstract for a short communication at the ICM itself.

ASL student travel awards. One of our sponsoring institutions, the Association for Symbolic Logic is offering modest travel awards to graduate students in logic to attend our conference. To be considered for a travel award, please (1) send a letter of application, and (2) ask your thesis supervisor to send a brief recommendation letter. The application letter should be brief (preferably one page) and should include: (1) your name; (2) your home institution; (3) your thesis supervisor's name; (4) a one-paragraph description of your studies and work in logic, and a paragraph indicating why it is important to attend the meeting; (5) your estimate of the travel expenses you will incur; (6) (for citizens or residents of the USA) citizenship or visa status; and (7) (voluntary) indication of your gender and minority status. Women and members of minority groups are strongly encouraged to apply. Applications should be sent by the deadline of 10 May 2018 to asl(at)vassar.edu with the subject line "ASL travel application for ICM 2018 satellite conference". The ASL expects to communicate decisions at least two months prior to the meeting. For more information, please check the ASL webpage on student travel awards.

Venue. The conference is organised by the Universidade Federal Fluminense (UFF) and will take place in the auditorium of the Museu de Arte Contemporânea de Niterói—MAC, the iconic symbol of the city of Niterói. The Museum was designed by the famous Brazilian architect Oscar Niemeyer and its viewing gallery provides stunning vistas of Guanabara Bay, Rio de Janeiro, and Sugerloaf Mountain. The city of Niterói is in the metropolitan area of Rio de Janeiro, on the other side of the Guanabara Bay, approximately a one hour drive from the site of the ICM 2018 (the Riocentro Convention & Event Center in the west of the city of Rio de Janeiro). We expect to organise a minibus for participants to transfer from the Riocentro to Niterói after the closing of the ICM 2018 on Thursday 9 August 2018:

Visa & other practical information. Note that citizens of Australia, Canada, the United States of America, and most countries in Asia need a visa to enter Brazil. A visa waiver programme exists for citizens of most countries in South America, Central America, and Europe. We refer the participants to the ICM visa page for more information and detailed links to official webpages. Please make sure that you check the visa requirements and, if needed, apply for a visa in due time.

For our invited speakers, we booked the H Hotel Niterói which is in walking distance of the conference venue. Other participants are requested to make their own accommodation arrangements (the H Hotel can be booked via their webpage).
