Temporal Description Logics: A Survey
We survey temporal description logics that are based on standard temporal logics such as LTL and CTL. In particular, we concentrate on the computational complexity of the satisfi...

Lower Bounds for Non-Black-Box Zero Knowledge
We show new lower bounds and impossibility results for general (possibly non-black-box) zero-knowledge proofs and arguments. Our main results are that, under reasonable complexity...

Computationally Private Information Retrieval with Polylogarithmic Communication
We present a single-database computationally private information retrieval scheme with polylogarithmic communication complexity. Our construction is based on a new, but reasonable...

Collapsibility in Infinite-Domain Quantified Constraint Satisfaction
In this article, we study the quantified constraint satisfaction problem (QCSP) over infinite domains. We develop a technique called collapsibility that allows one to give strong c...

Planning in Action Formalisms based on DLs: First Results
Abstract. In this paper, we continue the recently started work on integrating action formalisms with description logics (DLs), by investigating planning in the context of DLs. We p...
