A modal logic is called invariant if for all automorphisms of NExt K, () = . An invariant logic is therefore uniquely determined by its surrounding in the lattice. It will be est...
We discuss interesting properties of a general technique for inferring polynomial invariants for a subfamily of imperative loops, called the P-solvable loops, with assignments only...
In general, invariants may depend on the state of other objects. The approach introduced in this paper allows this for objects of mutually visible classes, in a way that supports ...
