Title: Width Hierarchies for Quantum and Classical Ordered Binary Decision Diagrams with Repeated Test,
Abstract: We consider quantum, nondterministic and probabilistic versions of known
computational model Ordered Read-$k$-times Branching Programs or Ordered Binary
Decision Diagrams with repeated test ($k$-QOBDD, $k$-NOBDD and $k$-POBDD). We
show width hierarchy for complexity classes of Boolean function computed by
these models and discuss relation between different variants of $k$-OBDD.
