A note on lifting projections
Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...
متن کاملIdeal Projections and forcing Projections
It is well known that saturation of ideals is closely related to the “antichain-catching” phenomenon from Foreman-Magidor-Shelah [10]. We consider several antichain-catching properties that are weaker than saturation, and prove: (1) If I is a normal ideal on ω2 which satisfies stationary antichain catching, then there is an inner model with a Woodin cardinal; (2) For any n ∈ ω, it is consistent...
متن کاملDemand for Long-Term Care: Projections of Long-Term Care Finance for Elderly People Research Bulletin
There has in recent years been some debate, and various analyses, concerning likely future demand for long-term care for elderly people. This has been prompted by the wider policy debate about how best to finance long-term care. The policy debate has culminated in the establishment of the Royal Commission on Long-Term Care for the Elderly. Its report was expected shortly as this Bulletin went t...
متن کاملWhere people die (1974--2030): past trends, future projections and implications for care.
BACKGROUND Ageing nations have growing needs for end of life care, but these have never been projected in detail. We analysed past trends in place of death (1974-2003) and projected likely trends to 2030 in England and Wales and from these need for care. METHODS Mortality trends and forecasts were obtained from official statistics. Future scenarios were modelled using recent five-year trends ...
