We report on work in progress devoted to the formalization of an Ordered Logical Framework (OLF) based on a two-level architecture [8] in the Hybrid system. OLF here is a second-or...
We report on work in progress regarding a foundation for the notion of meta-variable in logical frameworks and type theories. Our proposal is to treat meta-variables as modal varia...

I describe the mechanisation in HOL of some basic -calculus theory, using the axioms proposed by Gordon and Melham [4]. Using these as a foundation, I mechanised the proofs from C...
We propose a conservative extension of HM(X), a generic constraint-based type inference framework, with bounded existential (a.k.a. abstract) and universal (a.k.a. polymorphic) da...
We have verified several versions of the CPS transformation in Isabelle/HOL. In our verification we adopted first-order abstract syntax with variable names so that the formalizati...
