Dynamic Logic with Non-rigid Functions
We introduce a dynamic logic that is enriched by non-rigid functions, i.e., functions that may change their value from state to state (during program execution), and we present a (...

Termination and Reduction Checking for Higher-Order Logic Programs
In this paper, we present a syntax-directed termination and reduction checker for higher-order logic programs. The reduction checker verifies parametric higher-order subterm orderi...
