The Nondeterministic Information Logic NIL is PSPACE-complete
The nondeterministic information logic NIL has been introduced by Orlowska and Pawlak in 1984 as a logic for reasoning about total information systems with the similarity, the forw...

Many Facets of Complexity in Logic
There are many ways to define complexity in logic. In finite model theory, it is the complexity of describing properties, whereas in proof complexity it is the complexity of provin...

Succinct NP Proofs from an Extractability Assumption
Abstract We prove, using a non-standard complexity assumption, that any language in NP has a 1-round (that is, the verifier sends a message to the prover, and the prover sends a me...

If NP Languages are Hard on the Worst-Case, Then it is Easy to Find Their Hard Instances
We prove that if NP ⊆ BPP, i.e., if SAT is worst-case hard, then for every probabilistic polynomial-time algorithm trying to decide SAT, there exists some polynomially samplable ...

Generic Trace Theory
Trace semantics has been defined for various non-deterministic systems with different input/output types, or with different types of "non-determinism" such as classical ...
