LSFA 2019
14th Workshop on Logical and Semantic Frameworks, with Applications
24-26 August 2019, Natal, Brazil

Logical and semantic frameworks are formal languages used to represent logics, languages and systems. These frameworks provide foundations for the formal specification of systems and programming languages, supporting tool development and reasoning.

LSFA 2019 will be a satellite event of CADE-27, which will be held in Natal, Brazil, 25-30 August, 2019 ( Previous editions of LSFA took place in Fortaleza (2018), Brasília (2017, collocated with Tableaux+FroCoS+ITP), Porto (2016), Natal (2015), Brasília (2014), São Paulo (2013), Rio de Janeiro (2012), Belo Horizonte (2011), Natal (2010), Brasília (2009), Salvador (2008), Ouro Preto (2007), and Natal (2006). See for more information.


Topics of interest include, but are not limited to:

* Specification languages and meta-languages
* Formal semantics of languages and logical systems
* Logical frameworks
* Semantic frameworks
* Type theory
* Proof theory
* Automated deduction
* Implementation of logical or semantic frameworks
* Applications of logical or semantic frameworks
* Computational and logical properties of semantic frameworks
* Logical aspects of computational complexity
* Lambda and combinatory calculi
* Process calculi


Contributions should be written in English and submitted in the form of full papers with a maximum of 13 pages including references. Beyond full regular papers, we encourage submissions such as proof pearls, rough diamonds (preliminary results and work in progress), original surveys, or overviews of research projects, where the focus is more on elegance and dissemination than on novelty. Papers belonging to this second category are expected to be short, that is, of a maximum of 6 pages including references. For both paper categories, additional technical material can be provided in a clearly marked appendix which will be read by reviewers at their discretion. Contributions must also be unpublished and not submitted simultaneously for publication elsewhere.

The papers should be prepared in LaTeX using the generic ENTCS package ( The submission should be in the form of a PDF file uploaded to Easychair:

At least one of the authors should register for the workshop. All accepted papers will be available online during the workshop; full papers will be published at ENTCS, and short papers will be collected in an informal volume. For the publication of the proceedings there will be a cost to authors of USD 50 at registration time. Previous LSFA special issues have been published in journals such as Log J IGPL and TCS (see
