Neutrosophic Lattices [PDF]

open access: yesNeutrosophic Sets and Systems, 2014
In this paper authors for the first time define a new notion called neutrosophic lattices. We define few properties related with them. Three types of neutrosophic lattices are defined and the special properties about these new class of lattices are ...

The partially pre-ordered set of compactifications of Cp(X, Y)

open access: yesTopological Algebra and its Applications, 2015
In the set of compactifications of X we consider the partial pre-order defined by (W, h) ≤X (Z, g) if there is a continuous function f : Z ⇢ W, such that (f ∘ g)(x) = h(x) for every x ∈ X. Two elements (W, h) and (Z, g) of K(X) are equivalent, (W, h) ≡X (

Note on the Hahn-Banach Theorem in a Partially Ordered Vector Space

open access: yesJournal of Applied Mathematics, 2013
Using a fixed point theorem in a partially ordered set, we give a new proof of the Hahn-Banach theorem in the case where the range space is a partially ordered vector space.

A Novel Definition of L-Fuzzy Lattice Based on Fuzzy Set

open access: yesThe Scientific World Journal, 2013
The concept of L-fuzzy lattice is presented by means of an L-fuzzy partially ordered set. An L-fuzzy partially ordered set A is an L-fuzzy lattice if and only if one of A[a], A[a], and A(a) is a lattice.

Spanning retracts of a partially ordered set

open access: yes, 1980
Two general kinds of subsets of a partially ordered set P are always retracts of P: (1) every maximal chain of P is a retract; (2) in P, every isometric, spanning subset of length one with no crowns is a retract.

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

On chains and posets within the power set of a continuum

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
Transfinite induction is employed to construct a copy of an arbitrary partially-ordered set of cardinality at most c within the power set (quasi-ordered by sub-chain embeddability) of the real line.
