Counting and Addition Cannot Express Deterministic Transitive Closure
An important open question in complexity theory is whether the circuit complexity class TC0 is (strictly) weaker than LOGSPACE. This paper considers this question from the viewpoi...

Checking Emptiness of Non-Deterministic Regular Types with Set Operators
An algorithm to decide the emptiness of a regular type expression with set operators given a set of parameterized type definitions is presented. The algorithm generalizes previous...
