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 ‘(‘

Boolean algebras with no rigid or homogeneous factors
A simple construction of Boolean algebras with no rigid or homogeneous factors is described. It is shown that for every uncountable cardinal κ \kappa there are 2 κ {2^\kappa ...

A plasmonic optoelectronic memristor based on Te nanowires‐Au nanoparticles/ι‐carrageenan enables IR‐programmed and visiblelight‐erased non‐volatile conductance. The all‐photonic write/erase scheme supports in‐sensor logic and real‐time motion detection in darkness.

Abstract We explore configurations of sufficient and necessary conditions for the evolution and resilience of borrower trust in their lenders. Because trust is a dynamic phenomenon that needs to be understood in terms of change over time, we rely on longitudinal data collected from managers of small‐ and medium‐sized enterprises (SME) who are clients ...

A characterization of complete atomic Boolean algebras
In this note we give a characterization of complete atomic Boolean algebras by means of complete atomic lattices. We find that unicity of the representation of the maximum as union of atoms and Lambda-infinite distributivity law are necessary and ...

A note on ultraproducts of complete boolean algebras
In J. Pure Appl. Algebra 32, 11-20 (1984; Zbl 0539.13003), the author asserted that ultraproducts of Boolean algebras, whose cardinalities are approaching the first measurable cardinal k, over an index set of cardinality at least k, are necessarily incomplete.

A Boolean partition algebra is a pair $(B,F)$ where $B$ is a Boolean algebra and $F$ is a filter on the semilattice of partitions of $B$ where $\bigcup F=B\setminus\{0\}$.
