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 abstract, at least one author must register and attend the symposium (in person) to present it. Moreover, an author cannot register for multiple abstracts. That is, each accepted abstract must have its own registrant.

Proceedings

The abstracts of accepted submissions will not be formally published, but will be compiled into a Book of Abstracts that will be made available on the event website.

After the workshop, there will be a call for papers for a special issue of the 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.
