LAWCG 2026
12th Latin American Workshop on Cliques in Graphs
LAWCG is meant to foster interaction among the Latin American Graph Theory and Combinatorics community, whose research interests include cliques, clique graphs, the behavior of cliques and other topics in Graph Theory.
The official languages are English, Portuguese, and Spanish.

Submissions
Contributed talks covering original work on the conference topics will be accepted for presentation.
Prospective authors should submit an at most 2-page abstract of their work following this LaTeX format. Other formats will not be accepted for submission.
Papers must be submitted electronically via the EasyChair submission system.
For each accepted paper at least one author must register and attend the symposium (in person) to present it. Moreover, an author cannot register for multiple papers. That is, each accepted paper must have its own registrant.
Proceedings
The proceedings of the workshop will likely be published, after the event, at Matemática Contemporânea, as in the previous editions of LAWCG. All interested researchers will be invited to submit an extended abstract describing their contributions. The submitted papers will go through the normal peer-review process, following the guidelines of Matemática Contemporânea.

Program
A detailed program will be announced in due course. The event runs from 4:00 pm on 5 October to 2:00 pm on 8 October.
Registration
The event will take place at hotel Monte Real, and all participants are required to stay at this hotel for the duration of the event. The registration fee is all-inclusive and will cover accommodation, all meals, and leisure facilities at the hotel. It may also include transportation between São Paulo–Guarulhos International Airport (GRU) and the hotel.
Expenses for alcoholic and non-alcoholic beverages, as well as extra services such as minibar, laundry, and any other costs incurred by participants during their stay, will be the responsibility of the participants and must be paid at hotel check-out.
During registration, participants must choose between a single room or a shared double room. Selecting a single room will incur an additional cost. Participants in double rooms may indicate their preferred roommate during registration; if no preference is given, room assignments will be made by the organizing team.
Participants are welcome to bring accompanying guests, such as family members or children. Accompanying adults will pay a fee that is very similar to the main registration fee, while children will be charged a reduced rate.
More details regarding prices and transportation will be provided soon.
