Topos-Theoretic Approaches to Quantum Theory [PDF]

, 2012
Starting from a naive investigation into the nature of experiments on a physical system one can argue that states of the system should pair non-degenerately with physical observables. This duality is closely related to that between space and quantity, or,

A common approach to directoids with an antitone involution and D-quasirings

, 2008
We introduce the so-called DN-algebra whose axiomatic system is a common axiomatization of directoids with an antitone involution and the so-called D-quasiring. It generalizes the concept of Newman algebras (introduced by H.

On the Theory of Ring-Logics

, 1956
Boolean rings (B, ✗, + ) and Boolean logics ( = Boolean algebras) (B, ∩, *) are equationally interdefinable in a familiar way (6). Foster's theory of ring-logics (1; 2; 3) raises this interdefinability and indeed the entire Boolean theory to a more ...

The Subpower Membership Problem of 2-Nilpotent Algebras [PDF]

The subpower membership problem SMP() of a finite algebraic structure asks whether a given partial function from Aⁿ to A can be interpolated by a term operation of , or not. While this problem can be EXPTIME-complete in general, Willard asked whether it

Zero-dimensional Dugundji spaces admit profinite lattice structures [PDF]

, 1992
summary:We prove what the title says. It then follows that zero-dimensional Dugundji space are supercompact.

Closure-classes of Boolean functions

, 1972
In the study of real-valued set functions, there arise certain "regularity conditions" which impose restrictions upon the domains of definition of such functions. Examples of such regularity conditions are additivity, convexity etc. Well-known domains of
