Towards a Complex Variable Interpretation of Peirce’s Existential Graphs
monoid can be defined. Monoidal categories are ubiquitous: cartesian categories (in particular, the category of sets), free word-category over any category, endofunctors category over any category, category of R-modules over a commutative ring R, etc. The abstract monoids definable in the monoidal category incarnate in the usual monoids, triples (or monads), R-algebras, etc. 2 Given a monoidal ...
متن کاملDecoherence , einselection and the existential interpretation ( the rough guide )
The roles of decoherence and environment-induced superselection in the emergence of the classical from the quantum substrate are described. The stability of correlations between the einselected quantum pointer states and the environment allows them to exist almost as objectively as classical states were once thought to exist: there are ways of finding out what is the pointer state of the system...
متن کاملThe modular product and existential closure II
In this article we study the modular graph product, ♦, that is known to preserve the property of being 3-existentially closed (i.e., 3-e.c.). We produce new families of 3-e.c. graphs G♦H such that neither G nor H is required to be 3-e.c. Assuming that G is weakly 3-existentially closed with certain adjacency properties, we find the sufficient conditions on the adjacency properties of H such tha...
متن کاملUniform Positive Existential Interpretation of the Integers in Rings of Entire Functions of Positive Characteristic
We prove a negative solution to the analogue of Hilbert’s tenth problem for rings of one variable non-Archimedean entire functions in any characteristic. In the positive characteristic case we prove more: the ring of rational integers is uniformly positive existentially interpretable in the class of {0, 1, t,+, ·,=}-structures consisting of positive characteristic rings of entire functions on t...
متن کاملExistential Laughter
Each of the previous three articles in this series has examined one of the three main traditions of humour theory; those based around incongruity, superiority and the release of energy. We have seen that each of these theoretical traditions sheds some light upon humour and laughter, but also that all fail in their overly ambitious task of offering a fully comprehensive theory. This has not dete...
