Degenerate Metric Phase Boundaries
The structure of boundaries between degenerate and nondegenerate solutions of Ashtekar’s canonical reformulation of Einstein’s equations is studied. Several examples are given of such “phase boundaries” in which the metric is degenerate on one side of a null hypersurface and non-degenerate on the other side. These include portions of flat space, Schwarzschild, and plane wave solutions joined to...

Several examples are given of such \phase boundaries" in which the metric is degenerate on one side of a null hypersurface and non-degenerate on the other side.

متن کاملProtein-Polyelectrolyte Phase Boundaries
The separation of proteins by polyelectrolyte coacervation or precipitation is based on electrostatically-driven complex formation. We have investigated complexation between the globular protein BSA and the polyelectrolyte poly(dimethyldially1ammonium chloride) (PDMDAAC) using light-scattering techniques to monitor solution turbidity. Turbidimetric pH titrations were used to determine the speci...
متن کاملMetric Spaces in which All Triangles Are Degenerate Bettina
In any subspace of the real line R with the usual Euclidean metric d(x, y) = |x− y|, every triangle is degenerate. In R or R with the usual Euclidean metrics, a triangle is degenerate if and only if its vertices are collinear. With our intuition of a degenerate triangle having “collinear vertices” extended to arbitrary metric spaces, we might expect that a metric space in which every triangle i...
