The Proof Complexity of Polynomial Identities
Devising an efficient deterministic – or even a nondeterministic sub-exponential time – algorithm for testing polynomial identities is a fundamental problem in algebraic comp...

Two Dimensional Parameterized Matching
Two equal length strings, or two equal sized two-dimensional texts, parameterize match (p-match) if there is a one-one mapping (relative to the alphabet) of their characters. Two-...

Liveness with Invisible Ranking
The method of Invisible Invariants was developed originally in order to verify safety properties of parameterized systems fully automatically. Roughly speaking, the method is based...

Treewidth Reduction for Constrained Separation and Bipartization Problems
We present a method for reducing the treewidth of a graph while preserving all the minimal s−t separators. This technique turns out to be very useful in the design of parameteriz...

Local Proofs for Global Safety Properties
This paper explores the concept of locality in proofs of global safety properties of asynchronously composed, multi-process programs. Model checking on the full state space is ofte...
