## Abstract A graph with __n__ vertices is well covered if every maximal independent set is a maximum independent set and very well covered if every maximal independent set has size __n__/2. In this work, we study these graphs from an algorithmic complexity point of view. We show that well‐covered

Undecidability Results for Low Complexit
✍ Rod Downey; André Nies 📂 Article 📅 2000 🏛 Elsevier Science 🌐 English ⚖ 165 KB

We prove that the theory of Exptime degrees with respect to polynomial time Turing and many-one reducibility is undecidable. To do so we use a coding method based on ideal lattices of Boolean algebras which was introduced by Nies (1997, Bull. London Math. Soc. 29, 683 692). The method can be applied

New Lowness Results for ZPPNP and Other
✍ V. Arvind; Johannes Köbler 📂 Article 📅 2002 🏛 Elsevier Science 🌐 English ⚖ 242 KB

We show that the class AM \ coAM is low for ZPP NP . As a consequence, it follows that Graph Isomorphism and several group-theoretic problems are low for ZPP NP . We also show that the class IP½P=poly, consisting of sets that have interactive proof systems with honest provers in P=poly, is also low
