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...

Variables as Resource in Hoare Logics
Hoare logic is bedevilled by complex but coarse side conditions on the use of variables. We define a logic, free of side conditions, which permits more precise statements of a pr...

PSPACE Bounds for Rank-1 Modal Logics
aic semantics, which conveniently abstracts from the details of a given model class and thus allows covering a broad range of logics in a uniform way. Categories and Subject Descri...

A Functional Quantum Programming Language
We introduce the language QML, a functional language for quantum computations on finite types. Its design is guided by its categorical semantics: QML programs are interpreted by ...
