Algebraic Property Testing: The Role of Invariance
... does not seem to have been explicit in prior literature. We make it explicit here. We remark that in independent work, Goldreich and Sheffet [11], also make this notion explicit, and use it to understand the randomness complexity needs of property testing. In this paper we explore invariances of an ...

Integration theory
... We denote by R and R the real numbers and extended real numbers (i.e. including ±∞) respectively. We also let N = {1, 2, 3, . . .} denote the natural numbers and Q the rational numbers. Let X denote a non-empty set. For a function f : X → R the word positive means in its non-strict sense, so f is po ...

... 2. Approximating maps of finite simplicial complexes by embeddings If X is a topological space, a map f W X ! Rn is called an embedding if f is a homeomorphism onto its image. For compact X , it is equivalent to require that f be a continuous injection. When we speak of a finite simplicial complex, ...

It’s straightforward to show the transitivity of the relation of the homotoopy equivalence and it follows that this relation is an equivalence relation. And two spaces that are homotopy equivalent are sai ...

The map exp: o(n) → O(n) is well-defined, but it is not surjective, since there are matrices in O(n) with determinant −1 ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
