Fixed-Parameter Hierarchies inside PSPACE
Treewidth measures the ”tree-likeness” of structures. Many NP-complete problems, e.g., propositional satisfiability, are tractable on bounded-treewidth structures. In this wo...

Wreath Products of Forest Algebras, with Applications to Tree Logics
—We use the recently developed theory of forest algebras to find algebraic characterizations of the languages of unranked trees and forests definable in various logics. These i...
