Topic: Connected category theory


  
  Encyclopedia :: encyclopedia : Category theory   (Site not responding. Last check: 2007-10-31)
Category theory is a mathematical theory that deals in an abstract way with mathematical structures and relationships between them.
Categories appear in most branches of mathematics, in some areas of theoretical computer science and mathematical physics, and have been a unifying notion.
Categorical logic is now a well-defined field based on type theory for intuitionistic logics, with application to the theory of functional programming and domain theory, all in a setting of a cartesian closed category as non-syntactic description of a lambda calculus.

This labour theory of price and the closely related cost-of-production theory of value dominates the work of most classical economists, but those theories are far from the only accepted basis for "value".
Although the conventional way of connecting the economic model with the world is through econometric analysis, Professor Deirdre McCloskey cites many examples in which professors of econometrics were able to use the same data to both prove and disprove the applicability of a model's conclusions.

 SEP: Category Theory
Category theory is both an interesting object of philosophical study, and a potentially powerful formal tool for philosophical investigations of concepts such as space, system, and even truth.
Connections with intuitionistic mathematics were noted early on, and toposes are still used to investigate models of various aspects of intuitionism (Lambek and Scott 1986, Mac Lane and Moerdijk 1992, Van der Hoeven and Moerdijk 1984a, 1984b, 1984c, Moerdijk 1984, Moerdijk 1995a, Moerdijk 1998, Moerdijk and Palmgren 1997, Moerdijk and Palmgren 2002).
Category theory is, in this sense, the legitimate heir of the Dedekind-Hilbert-Noether-Bourbaki tradition, with its emphasis on the axiomatic method and algebraic structures.

In any case, Duesberg’s credibility has been damaged because the preponderance of evidence supports the HIV theory and not Duesberg’s largely unsupported claims, not because anyone “did” something to him.
But we do have theories of how AZT works, and recipients of AZT and other AIDS drugs have been monitored very carefully since their introduction to determine the results.
It is the exact opposite - if there is a theory underlying all complementary medicine, it is that the human body works quite well on its own and needs tweaking as little and as naturally as possible.
