Partitioned Balancing Domain Decomposition Method for Heterogeneous Static Structures

International Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.
ABSTRACT This study proposes a partitioned balancing domain decomposition (P‐BDD) method for static analysis of heterogeneous structures. The P‐BDD method may be viewed as a localized version of traditional BDD approaches. Its principal solution vector consists of unassembled partition‐boundary displacements, used to compute the partition‐interior ...

Boundary Algebra: A Simple Notation for Boolean Algebra and the Truth Functors [PDF]

Boundary algebra [BA] is a simpler notation for Spencer-Brown’s (1969) primary algebra [pa], the Boolean algebra 2, and the truth functors. The primary arithmetic [PA] consists of the atoms ‘()’ and the blank page, concatenation, and enclosure between ‘(‘

Many-Valued Logic and Zadeh’s Fuzzy Sets: A Stone Representation Theorem for Interval-Valued Łukasiewicz–Moisil Algebras

Journal of Intelligent Systems, 2016
The aim of this article is to develop a representation theory of interval-valued Łukasiewicz–Moisil algebras; the concept of interval fuzzy sets involves the role that the notion of field of sets plays for the representation of Boolean algebras.

Cardinal invariants on Boolean algebras

, 2014
This book is concerned with cardinal number valued functions defined for any Boolean algebra. Examples of such functions are independence, which assigns to each Boolean algebra the supremum of the cardinalities of its free subalgebras, and cellularity ...

Totally disconnected compactifications

International Journal of Mathematics and Mathematical Sciences, 1993
There is a one-to-one order preserving correspondence between totally disconnected compactifications of a topological space and certain Boolean algebras of open closed subsets on it.

Reconstructing Classical Algebras via Ternary Operations

Mathematics
Although algebraic structures are frequently analyzed using unary and binary operations, they can also be effectively defined and unified using ternary operations.

Symmetric Boolean Algebras

, 2006
We define Boolean algebras in the linear context and study its symmetric powers. We give explicit formulae for products in symmetric Boolean algebras of various dimensions. We formulate symmetric forms of the inclusion-exclusion principle.

Some results on pseudo MV-algebras with n-roots

Ratio Mathematica
The paper provides a study of pseudo MV-algebras with $n$-roots. We outline their main properties and establish that the class of MV-algebras with $n$-roots forms a variety.
