Ghost busting: Making sense of non-Hermitian Hamiltoniansy. The proof of unitarity requires the construction of a time-independent operator called .. In terms of . one can define a new inner product with respect to which the norms of the states in the Hilbert space are positive. Furthermore, it has been shown that time evolution in such a theory is unitar

Automated Debugging for Logic Bugsts importance in the analysis of the Noumi-Yamada system (a particular higher order Painlevé equation) and a concrete recipe for locating them. Examples given here make it manifest that virtual turning points are indispensable in WKB analysis of higher order linear ordinary differential equations wi
