Constructing Homogeneous Gorenstein Ideals
In 1983 Kustin and Miller introduced a construction of Gorenstein ideals in
local Gorenstein rings, starting from smaller such ideals. We review and modify
their construction in the case of graded rings and discuss it within the
framework of Gorenstein liaison theory. We determine invariants of the
constructed ideal. Concerning the problem of when a given Gorenstein ideal can
be obtained by the construction, we derive a necessary condition and exhibit a
Gorenstein ideal that can not be obtained using the construction
SPS construction perspective. Summary
Projections concerning the general construction requirements for a solar power satellite (SPS) are summarized. It is recognized that the ability to construct an SPS must be developed through an evolutionary process. This process would begin with shuttle operations and when construction timelines exceed the shuttle capability, small manned bases in low Earth orbit (LEO) would be used. The influence of construction methods on design, assembly bases, and crew considerations are addressed
