Hierarchies of complete problems

Acta Informatica, 1976
An attempt is made to present a framework for the diverse complete problems that have been found. A new concept--a Hierarchy of Complete Problems is defined. Several hierarchies in various domains such as graph theory, automata theory, theorem proving and games are established.

The problem of hierarchy in government

1996 International Symposium on Technology and Society Technical Expertise and Public Decisions. Proceedings, 2002
Hierarchical ways of managing government are no longer relevant in an information intensive world. Information technology can provide the means to transform governments into more responsive and accountable organizations. However, despite significant investments in information technology and efforts to move toward flatter organizational structures ...

The gauge hierarchy problem

Journal of Physics G: Nuclear Physics, 1982
Discusses the problem of gauge hierarchy in grand unified theories using a toy model with O(N) symmetry to illustrate the authors' statements. They show that there is no escape from the unnatural adjustment of coupling constants, made only after the computation to several orders in perturbation theory is performed. They comment on the proposals of some

A hierarchy of Sturm–Liouville problems

Mathematical Methods in the Applied Sciences, 2003
AbstractSturm–Liouville equations will be considered where the boundary conditions depend rationally on the eigenvalue parameter. Such problems apply to a variety of engineering situations, for example to the stability of rotating axles. Classesof these problems will be isolated with a rather rich spectral structure, for example oscillation, comparison
