On Semilattice Structure of Mizar Types
Let us mention that every non empty relational structure which is trivial and reflexive is also complete. Let T be a relational structure. A type of T is an element of T . Let T be a relational structure. We say that T is Noetherian if and only if: (Def. 1) The internal relation of T is reversely well founded. Let us observe that every non empty relational structure which is trivial is also Noe...
متن کاملAdjoint Semilattice and Minimal Brouwerian Extensions of a Hilbert Algebra*
Let A := (A,→, 1) be a Hilbert algebra. The monoid of all unary operations on A generated by operations αp : x → (p → x), which is actually an upper semilattice w.r.t. the pointwise ordering, is called the adjoint semilattice of A. This semilattice is isomorphic to the semilattice of finitely generated filters of A, it is subtractive (i.e., dually implicative), and its ideal lattice is isomorph...
متن کاملThe canonical topology on a meet-semilattice
Considering the lattice of properties of a physical system, it has been argued elsewhere that – to build a calculus of propositions having a well-behaved notion of disjunction (and implication) – one should consider a very particular frame completion of this lattice. We show that the pertinent frame completion is obtained as sheafification of the presheaves on the given meet-semilattice with re...
متن کاملIdeals of Pre A ∗ - Algebra
In this paper we formulate the definition of an ideal of Pre A∗-algebra A and discuss certain examples. Also certain binary operations are introduced on the set of ideals and various properties of these are investigated. Copyright c © 2011 Yang’s Scientific Research Institute, LLC. All rights reserved.
متن کاملStructure of Certain Banach Algebra Products
Let and be Banach algebras, , and . We define an -product on which is a strongly splitting extension of by . We show that these products form a large class of Banach algebras which contains all module extensions and triangular Banach algebras. Then we consider spectrum, Arens regularity, amenability and weak amenability of these products.
