PROFILE
Markus Gschoßmann
Worked on foundational research and system design for the nipkow/AIST repository, focusing on establishing a Generalized Normal Form (GNF) grammar theory within the context of formal language theory and automated theorem proving. Developed a partial existence framework for GNF grammars and initiated code refactoring to support future proof strategies. Used Isabelle/HOL and Isabelle/ML to formalize equivalence proofs, splitting main theorems for clarity and maintainability. Documented unresolved lemmas and non-provability notes to guide ongoing research and prevent redundant efforts. Prepared the groundwork for downstream CNF conversion and grammar transformations, setting up a structured path for future formal verification work.
