Linearity & TLLA
Joint Workshop on Linearity and Trends in Linear Logic and Applications
This workshop aims at bringing together researchers who are currently developing theory and applications of linear calculi or use linear logic as a technical tool or a methodological guidline, to foster their interaction and provide a forum for presenting new ideas and work in progress, and enable newcomers to learn about current activities in this area. Linearity is a key feature in both theoretical and practical approaches to computer science, and the goal of this workshop is to present work exploring linearity both in theory and practice. The addressed topics include proof representation, operational, static and dynamical models of programming languages, linear languages and type systems, parallelism and concurrency, quantum and probabilist computation, as well as philosophy and linguistics.

Proof Ground - Interactive Proving Contests
This workshop brings together researchers theorem proving enthusiasts to discuss and compete in “proving contests”. While programming contests (e.g. ACM ICPC, International Olympiad in Informatics) challenge large numbers of participants to solve algorithmic problems within a short time, we envision proving contests to entice proof engineers to formally prove small but interesting problems from mathematics or computer science. An existing contest system ( has been used to organize online proving contests where participants can solve tasks using Coq, Lean, or Isabelle. The workshop will be organized around an on-site contest, supplemented with informal discussions. We welcome participation from users of proof assistants which are not supported by the system.

International Workshop on Logical Frameworks and Meta-Languages: Theory and Practice
Logical frameworks and meta-languages form a common substrate for representing, implementing, and reasoning about a wide variety of deductive systems of interest in logic and computer science. Their design and implementation on the one hand and their use in reasoning tasks ranging from the correctness of software to the properties of formal computational systems on the other hand have been the focus of considerable research over the last three decades. This workshop will bring together designers, implementors, and practitioners to discuss various aspects impinging on the structure and utility of logical frameworks, including the treatment of variable binding, inductive and co-inductive reasoning techniques, and the expressivity and lucidity of the reasoning process.

International Workshop on Computing with Terms and Graphs
Graphs, and graph transformation systems, are used in many areas within Computer Science: to represent data structures and algorithms, to define models of computation, as a general modelling tool to study complex systems, etc. When computing with graphs rather than terms, common subexpressions can be shared, thus improving the efficiency of computations in space and time. Sharing is ubiquitous in implementations of programming languages: many functional, logic, object-oriented and concurrent calculi are implemented using graphs. TERMGRAPH 2020 will solicit papers describing new results relating to the theory or practical applications of graph transformation systems.

Workshop on Satisfiability Checking and Symbolic Computation
Symbolic Computation is concerned with the algorithmic determination of exact solutions to complex mathematical problems; recent developments in the area of Satisfiability Checking are starting to tackle similar problems but with different algorithmic and technological solutions. The two communities share many central interests, but researchers from these two communities rarely interact. Also, the lack of common or compatible interfaces of tools is an obstacle to their fruitful combination. Bridges between the communities in the form of common platforms and road-maps are necessary to initiate an exchange, and to support and direct their interaction. The aim of the SC2 workshop is to provide fertile ground to discuss, share knowledge and experience across both communities.
