Transforming structures by set interpretations

Thomas Colcombet ; Christof Löding.

We consider a new kind of interpretation over relational structures: finite sets interpretations. Those interpretations are defined by weak monadic second-order (WMSO) formulas with free set variables. They transform a given structure into a structure with a domain consisting of finite sets of&nbsp;[&hellip;]

Modeling and Verification of Infinite Systems with Resources

Martin Lang ; Christof Löding.

We consider formal verification of recursive programs with resource consumption. We introduce prefix replacement systems with non-negative integer counters which can be incremented and reset to zero as a formal model for such programs. In these systems, we investigate bounds on the resource&nbsp;[&hellip;]
