## Call for papers

Topics of interest to the 2026 Joint Symposium reflect both of its constituent communities. These topics include, but are not limited to, the following. Formal methods (including logic-based, category-theoretic and algebraic methods) applied to programs or to program frameworks. Of particular interest are uses of these methods that pertain to declarative languages or to AI-generated code. Aspects include. Synthesis, abstract interpretation, control flow, data flow, resource analysis, termination analysis, type inference and type checking. Verification, dynamic analysis, testing and certification. Applications of such formal methods to systems such as security, cyber-physical and distributed systems; as well as tools and industrial practices. All other aspects of declarative languages such as Uses for symbolic AI or for neuro-symbolic frameworks such as probabilistic or differentiable languages. Declarative language design: domain-specific languages; concurrency, parallelism and distribution; logic programming, functional languages; reactive languages; objects; languages for quantum computing; languages inspired by biological or chemical computation. Foundations: type theory, categories, complexity results, termination, logical semantics. Implementations: abstract machines; interpreters; compilation; compile-time and run-time optimization; memory management guarantees. Tools and Applications: programming and proof environments; verification tools; case studies in proof assistants or interactive theorem provers; novel applications of declarative programming inside and outside of CS; declarative programming pearls.
