The boundary manifold of a complex line arrangement [PDF]

open access: yes, 2008
We study the topology of the boundary manifold of a line arrangement in CP^2, with emphasis on the fundamental group G and associated invariants. We determine the Alexander polynomial Delta(G), and more generally, the twisted Alexander polynomial ...

Archimedean Atomic Lattice Effect Algebras with Complete Lattice of Sharp Elements [PDF]

open access: yes, 2010
We study Archimedean atomic lattice effect algebras whose set of sharp elements is a complete lattice. We show properties of centers, compatibility centers and central atoms of such lattice effect algebras. Moreover, we prove that if such effect algebra $

Notes on divisible MV-algebras

open access: yes, 2016
In these notes we study the class of divisible MV-algebras inside the algebraic hierarchy of MV-algebras with product. We connect divisible MV-algebras with $\mathbb Q$-vector lattices, we present the divisible hull as a categorical adjunction and we ...

An analysis of the logic of Riesz Spaces with strong unit

open access: yes, 2017
We study \L ukasiewicz logic enriched with a scalar multiplication with scalars taken in $[0,1]$. Its algebraic models, called {\em Riesz MV-algebras}, are, up to isomorphism, unit intervals of Riesz spaces with a strong unit endowed with an appropriate ...

Representation of Perfect and Local MV-algebras

open access: yes, 2010
We describe representation theorems for local and perfect MV-algebras in terms of ultraproducts involving the unit interval [0,1]. Furthermore, we give a representation of local Abelian lattice-ordered groups with strong unit as quasi-constant functions ...

States and synaptic algebras

open access: yes, 2016
Different versions of the notion of a state have been formulated for various so-called quantum structures. In this paper, we investigate the interplay among states on synaptic algebras and on its sub-structures.

An explicit realization of logarithmic modules for the vertex operator algebra W_{p,p'}

open access: yes, 2012
By extending the methods used in our earlier work, in this paper, we present an explicit realization of logarithmic $\mathcal{W}_{p,p'$}-modules that have L(0) nilpotent rank three.

Positive scalar curvature and product formulas for secondary index invariants

open access: yes, 2015
We introduce partial secondary invariants associated to complete Riemannian metrics which have uniformly positive scalar curvature outside a prescribed subset on a spin manifold.

The Notion of Radical Ideals in MV-Algebras and Product MV-Algebras

open access: yesStatistics, Optimization & Information Computing
In this work, we describe an interpretation of the radical of an ideal in the context of lu-groups, semi-low lu-rings and PMVf -algebras. These notions result naturally from a known notion in the context of MV-algebras and the use of categorical equivalences.
