Semilattice Structures of Spreading Models
Given a Banach space X, denote by SPw(X) the set of equivalence classes of spreading models of X generated by normalized weakly null sequences in X. It is known that SPw(X) is a semilattice, i.e., it is a partially ordered set in which every pair of elements has a least upper bound. We show that every countable semilattice that does not contain an infinite increasing sequence is order isomorphi...
متن کاملSpreading models isometric to `p or c0: The number of spreading models of a sequence
We introduce methods to “count” the number of spreading models generated by a sequence and prove the following dichotomy. Every basic sequence in a Banach space X has a normalized block basis (xn) which satisfies one and only one of the following two conditions: (1) (xn) determines a spreading model isometric to `p or c0 over X; (2) There exists a separable Banach space Y that contains (xn) and...
متن کاملLattice Structures and Spreading Models
We consider problems concerning the partial order structure of the set of spreading models of Banach spaces. We construct examples of spaces showing that the possible structure of these sets include certain classes of finite semi-lattices and countable lattices and all finite lattices.
متن کاملModels of EFL Learners’ Vocabulary Development: Spreading Activation vs. Hierarchical Network Model
Semantic network approaches view organization or representation of internal lexicon in the form of either spreading or hierarchical system identified, respectively, as Spreading Activation Model (SAM) and Hi- erarchical Network Model (HNM). However, the validity of either model is amongst the intact issues in the literature which can be studied through basing the instruction compatible wi...
متن کاملProjects With Sequential Iteration: Models and Complexity
Many new product development (NPD) projects are inherently complex, making effective management of the tasks, resources, and teams necessary to bring new products to market problematic. Frequently, managers of such NPD projects are overwhelmed by complicating factors such as stochastic task times, ill-defined specifications, complex interrelationships between tasks, and information dependencies...
