AFFILIATED WORKSHOPS --------------------

- HoTT/UF: 6th Workshop on Homotopy Type Theory/Univalent Foundations - ITRS: 10th Workshop on Intersection Types and Related Systems - WPTE: 7th International Workshop on Rewriting Techniques for Program Transformations and Evaluation - UNIF: 35th International Workshop on Unification - LSFA: 16th Logical and Semantics Frameworks with Applications - IWC: 10th International Workshop on Confluence - IFIP WG 1.6: 24th meeting of the IFIP Working Group 1.6: Rewriting

FSCD (http://fscd-conference.org/) covers all aspects of formal structures for computation and deduction from theoretical foundations to applications. Building on two communities, RTA (Rewriting Techniques and Applications) and TLCA (Typed Lambda Calculi and Applications), FSCD embraces their core topics and broadens their scope to closely related areas in logics, models of computation, semantics and verification in new challenging areas.

The suggested, but not exclusive, list of topics for submission is:

1. Calculi: - Rewriting systems (string, term, higher-order, graph, conditional, modulo, infinitary, etc.); - Lambda calculus; - Logics (first-order, higher-order, equational, modal, linear, classical, constructive, etc.); - Proof theory (natural deduction, sequent calculus, proof nets, etc.); - Type theory and logical frameworks; - Homotopy type theory; - Quantum calculi.

2. Methods in Computation and Deduction: - Type systems (polymorphism, dependent, recursive, intersection, session, etc.); - Induction, coinduction; - Matching, unification, completion, orderings; - Strategies (normalization, completeness, etc.); - Tree automata; - Model building and model checking; - Proof search and theorem proving; - Constraint solving and decision procedures.

3. Semantics: - Operational semantics and abstract machines; - Game Semantics and applications; - Domain theory and categorical models; - Quantitative models (timing, probabilities, etc.); - Quantum computation and emerging models in computation.

4. Algorithmic Analysis and Transformations of Formal Systems: - Type Inference and type checking; - Abstract Interpretation; - Complexity analysis and implicit computational complexity; - Checking termination, confluence, derivational complexity and related properties; - Symbolic computation.

5. Tools and Applications: - Programming and proof environments; - Verification tools; - Proof assistants and interactive theorem provers; - Applications in industry; - Applications of formal systems in other sciences.

6. Semantics and Verification in new challenging areas: - Certification; - Security; - Blockchain protocols; - Data Bases; - Deep learning and machine learning algorithms; - Planning.

PUBLICATION ----------- The proceedings will be published as an electronic volume in the Leibniz International Proceedings in Informatics (LIPIcs) of Schloss Dagstuhl. All LIPIcs proceedings are open access.

SPECIAL ISSUE ------------- Authors of selected papers will be invited to submit an extended version to a special issue of Logical Methods in Computer Science.

SUBMISSION GUIDELINES --------------------- The submission site is:

https://easychair.org/conferences/?conf=fscd2021

Submissions can be made in two categories. Regular research papers are limited to 15 pages, excluding references and appendices. They must present original research which is unpublished and not submitted elsewhere. System descriptions are limited to 15 pages (including references) and must present new software tools in which FSCD topics play an important role, or significantly new versions of such tools. An archive of the code with instructions on how to install and run the tool must be submitted. In addition, a webpage where the system can be experimented with should be provided. Complete instructions on submitting a paper can be found on the conference web site:

https://fscd2021.dc.uba.ar/

One author of an accepted paper is expected to present it at the conference

BEST PAPER AWARD BY JUNIOR RESEARCHERS -------------------------------------- The program committee will select a paper in which at least one author is a junior researcher, i.e. either a student or whose PhD award date is less than three years from the first day of the meeting. Other authors should declare to the PC Chair that at least 50% of contribution is made by the junior researcher(s).
