WebbMapping Reducibility If there is a mapping reduction from language A to language B, we say that language A is mapping reducible to language B. Notation: A ≤ M B iff language A is mapping reducible to language B. Note that we reduce languages, not machines. Interesting exercise: Show ≤ M is reflexive and transitive, but not antisymmetric. WebbWhat is Reducibility? A reduction is a way of converting one problem to another such that the solution to the second can be used to solve the first – We say that problem A is …

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 … In computability theory, many reducibility relations (also called reductions, reducibilities, and notions of reducibility) are studied. They are motivated by the question: given sets $${\displaystyle A}$$ and $${\displaystyle B}$$ of natural numbers, is it possible to effectively convert a method for deciding … Visa mer A reducibility relation is a binary relation on sets of natural numbers that is • Reflexive: Every set is reducible to itself. • Transitive: If a set $${\displaystyle A}$$ is reducible to a set $${\displaystyle B}$$ and $${\displaystyle B}$$ is … Visa mer • Stanford Encyclopedia of Philosophy: Recursive Functions Visa mer The strong reducibilities include • One-one reducibility: $${\displaystyle A}$$ is one-one reducible to $${\displaystyle B}$$ if there is a computable one-to-one function Visa mer Although Turing reducibility is the most general reducibility that is effective, weaker reducibility relations are commonly studied.

In computability theory and computational complexity theory, a reduction is an algorithm for transforming one problem into another problem. A sufficiently efficient reduction from one problem to another may be used to show that the second problem is at least as difficult as the first. Intuitively, problem A is reducible to problem B, if an algorithm for solving probl… 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 …
