Dynamic Complexity Theory Revisited
Dynamic complexity investigates the required effort to maintain knowledge about a property of a structure under changing operations. This article introduces a refined notion of ...

The Round Complexity of Verifiable Secret Sharing Revisited
The round complexity of interactive protocols is one of their most important complexity measures. In this work we prove that existing lower bounds for the round complexity of VSS c...

Rounds in Communication Complexity Revisited
The k-round two-party communication complexity was studied in the deterministic model by [14] and [4] and in the probabilistic model by [20] and [6]. We present new lower bounds th...

Revisiting Matrix Interpretations for Polynomial Derivational Complexity of Term Rewriting
Matrix interpretations can be used to bound the derivational complexity of term rewrite systems. In particular, triangular matrix interpretations over the natural numbers are known...

The communication complexity of the Exact-N Problem revisited
If Alice has x, y, Bob has x, z and Carol has y, z can they determine if x + y + z = N? They can if (say) Alice broadcasts x to Bob and Carol; can they do better? Chandra, Furst, a...
