Shuffling Lattices
نویسنده
چکیده
C. Greene (J. Combin. Theory Ser. A 47 (1988), 126-131) studied a family of lattices denoted ~K,,.,. In this paper, we generalize his work by defining a new operation on ordered pairs of lattices called shuffling. L1 shuffle L2 is denoted by L 1 M L2. The resulting L 1 M L 2 are not necessarily lattices but are posets. The lattices ~/U~, n correspond to the special cases N, ~ Nm. In this paper, we study the combinatorial structure of the shuffling operation and the resulting posets. © 1994 Academic Press, Inc.

Achieving Integrated Care for Older People: Shuffling the Deckchairs or Making the System Watertight For the Future?
Integrated care has been recognised as a key initiative to resolve the issues surrounding care for older people living with multi-morbidity. Multiple strategies and policies have been implemented to increase coordination of care globally however, evidence of effectiveness remains mixed. The reasons for this are complex and multifactorial, yet many strategies deal with parts of the problem rathe...
متن کاملRegularity in residuated lattices
In this paper, we study residuated lattices in order to give new characterizations for dense, regular and Boolean elements in residuated lattices and investigate special residuated lattices in order to obtain new characterizations for the directly indecomposable subvariety of Stonean residuated lattices. Free algebra in varieties of Stonean residuated lattices is constructed. We introduce in re...
متن کاملCare Integration – From “One Size Fits All” to Person Centred Care; Comment on “Achieving Integrated Care for Older People: Shuffling the Deckchairs or Making the System Watertight for the Future?”
Integrating services is a hot topic amongst health system policy-makers and healthcare managers. There is some evidence that integrated services deliver efficiencies and reduce service utilisation rates for some patient populations. In their article on Achieving Integrated Care for Older People, Gillian Harvey and her colleagues formulate some critical insights from practice and research around...
متن کاملAn equivalence functor between local vector lattices and vector lattices
We call a local vector lattice any vector lattice with a distinguished positive strong unit and having exactly one maximal ideal (its radical). We provide a short study of local vector lattices. In this regards, some characterizations of local vector lattices are given. For instance, we prove that a vector lattice with a distinguished strong unit is local if and only if it is clean with non no-...
متن کاملA characterization of multiwavelet packets on general lattices
The objective of this paper is to establish a complete characterization of multiwavelet packets associated with matrix dilation on general lattices $Gamma$ in $mathbb R^d$ by virtue of time-frequency analysis, matrix theory and operator theory.
