We find the number of partitions of n whose BG-rank is j, in terms of pp(n), the number of pairs of partitions whose total number of cells is n, giving both bijective and generati...
Based on the FOCUS theory of distributed systems (see [Broy, Stølen 01]) that are composed of interacting components we introduce a formal model of services and layered architectu...
We show how to automatically verify that complex XScale-like pipelined machine models satisfy the same safety and liveness properties as their corresponding instruction set archit...
Once you have proved your refinement correct, that is not the end. Real products, and their accompanying specifications, develop over time, with new improved versions having added...
We present a tool for automatic generation of packed bitfields and tagged unions for systems-level C, along with automatic, machine checked refinement proofs in Isabelle/HOL. Our a...
