WebbRANK-REDUCIBILITY OF A SYMMETRIC MATRIX AND SAMPLING THEORY. One of the intriguing questions of factor analysis is the extent to which one can reduce the rank of a symmetric matrix by only changing its diagonal entries. We show in this paper that the set of matrices, which can be reduced to rank r, has positive (Lebesgue) measure if and only … Webb26 feb. 2024 · Russell’s axiom of reducibility. The axiom of reducibility states that any truth function (i.e. propositional function) can be expressed by a formally equivalent predicative truth function. It made its first appearance in Bertrand Russell’s (1908) Mathematical logic as based on the theory of types, but only after some five years of trial ...

WebbIn these notes I give an introduction to the theory of complete reducibility and its applications, and explain an approach to the subject using geometric invariant theory. These notes are based on a series of six lectures delivered at the International Workshop on \Algorithmic problems in group theory, and related areas", held at the Oasis Summer Webb1 mars 2005 · We use geometric methods to investigate G -completely reducible subgroups of G, giving new criteria for G -complete reducibility. We show that a subgroup of G is G -completely reducible if and only if it is strongly reductive in G; this allows us to use ideas of R.W. Richardson and Hilbert–Mumford–Kempf from geometric invariant …

Webb12 nov. 2014 · Since each of the higher-level sciences is according to our criterion presumably also directly reducible to physics, reducibility turns out to be an asymmetric and transitive relation.

Webb21 maj 1996 · Philosophers soon followed Ludwig Wittgenstein (1922) and disputed the idea that these additional axioms, the axioms of reducibility and infinity, are really logical truths, and so denied that the logicist program of reducing arithmetic to logic was any more successful than Frege’s attempt had been.
