LSFA is an International Workshop on Logical and Semantic Frameworks
with Applications. Logical and semantic frameworks are
formal languages used to represent logics, languages and
systems. These frameworks provide mathematical foundations for
formal specification of systems and programming languages,
supporting tool development and reasoning.
The objective of this series is to put together
theoreticians and practitioners to promote new techniques and results,
from the theoretical side, and feedback on the implementation and use
of such techniques and results, from the practical side.
LSFA started in 2006 in Natal (LSFA06)
and its second and third editions were held in Ouro Preto
Salvador (LSFA08) always as a satellite event to the
Brazilian Symposium on Formal Methods (SBMF).
In 2009 (LSFA09) it was held as a satellite event of
RDP in Brasília, and
subsequently, LSFA was a satellite event of ICTAC in Natal (LSFA10).
Since its sixth edition it was held alone in
Belo Horizonte (LSFA11),
Rio de Janeiro and Niteroi (LSFA12),
São Paulo (LSFA13),
Brasília (LSFA14) and
then in Natal (LSFA15)
as part of NAT@Logic 2015. The eleventh edition, (LSFA16), was
held as satellite event of FSCD 2016 in
Porto, the twelth edition, LSFA 2017, in
Brasília, as satellite of the collocated
conferences Tableaux+FroCoS+ITP, the thirteen
2018 was held alone in Fortaleza, and the
fourteen edition, LSFA 2019 was held as satellite of CADE 2019
The Fifteen Logical and Semantic Framework with applications, LSFA
2020, will take place in Bahia.

- The Steering Committee selects its own chair(s).
- Each Steering Committee member serves until the third subsequent conference. In each conference, at most one third of the members of the SC can be renewed. In order to keep this balance, exceptionally and with the approval of the General Assembly, it is possible to extend for one year the term of some of the members of the SC.
- The General Assembly of each conference votes by secret ballot for new
Steering Committee members to replace the outgoing members. The maximum number of candidate indications allowed for each attendee of the General Assembly equals the number of open positions in that election. The total indications
per candidate are computed and the most voted, up to the number of
open positions, will be considered elected.
- Provide support to the Program Committee and Meeting Committee.
- Propose Program Committee chair, site and tentative date of meeting
to be held in next two years.
- Advertising and other issues concerning publicity of the conference.
- Act as liaison with other conferences and workshops.
- Call and organize the General Assembly.
- Organize the election of new Steering Committee members.
