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 کاملOptimal Type Lifting Optimal Type Lifting
Modern compilers for ML-like polymorphic languages have used explicit run-time type passing to support advanced optimizations such as intensional type analysis, representation analysis and tagless garbage collection. Unfortunately, maintaining type information at run time can incur a large overhead to the time and space usage of a program. In this paper, we present an optimal type-lifting algor...
متن کاملPerformance of a bimanual load-lifting task by parkinsonian patients.
Normal subjects and Parkinsonian patients performed a bimanual load lifting task. In this task, one "postural" forearm, held in a horizontal position while supporting a 1 kg weight, was unloaded either by the experimenter's hand (imposed unloading) or by the subject's other hand in response to a tone burst (voluntary unloading). The variables recorded were reaction time (RT: time interval betwe...
متن کامل[Moving and lifting patients: postural and ergonomic aspects].
The most dangerous and difficult tasks faced by health workers are those procedures involved with lifting and moving patients. Therefore, training and recycling programs in lifting procedures are a compulsory part of programs for the prevention of musculoskeletal disorders in schools and health institutions. The present study presents basic and innovative orientation with an ergonomic approach ...
متن کاملGENERALIZATIONS OF delta-LIFTING MODULES
In this paper we introduce the notions of G∗L-module and G∗L-module whichare two proper generalizations of δ-lifting modules. We give some characteriza tions and properties of these modules. We show that a G∗L-module decomposesinto a semisimple submodule M1 and a submodule M2 of M such that every non-zero submodule of M2 contains a non-zero δ-cosingular submodule.
