A projective basis is + points in general position, in a projective space of dimension n. A convex basis of a polytope is the set of the vertices of its convex hull. A cone basis [5] consists of one point by edge of a polygonal cone. See also a Hilbert basis (linear programming).
In mathematics, a basis function is an element of a particular basis for a function space. Every function in the function space can be represented as a linear combination of basis functions, just as every vector in a vector space can be represented as a linear combination of basis vectors .
A basis (or reference frame) of a (universal) algebra is a function that takes some algebra elements as values () and satisfies either one of the following two equivalent conditions. Here, the set of all b ( i ) {\displaystyle b(i)} is called the basis set , whereas several authors call it the "basis".
The first BASIS Curriculum School, BASIS Tucson, was founded in Tucson in 1998 by Michael Block and Olga Block, intending to educate students at an internationally competitive level. In 2003, BASIS Scottsdale was opened. In 2010, BASIS Oro Valley was founded. A year later, BASIS opened three schools at once in Chandler, Peoria, and Flagstaff. [6]
The set Γ of all open intervals in forms a basis for the Euclidean topology on .. A non-empty family of subsets of a set X that is closed under finite intersections of two or more sets, which is called a π-system on X, is necessarily a base for a topology on X if and only if it covers X.
Every vector a in three dimensions is a linear combination of the standard basis vectors i, j and k.. In mathematics, the standard basis (also called natural basis or canonical basis) of a coordinate vector space (such as or ) is the set of vectors, each of whose components are all zero, except one that equals 1.

The Franklin system is another Schauder basis for C([0, 1]), [12] and it is a Schauder basis in L p ([0, 1]) when 1 ≤ p < ∞. [13] Systems derived from the Franklin system give bases in the space C 1 ([0, 1] 2) of differentiable functions on the unit square. [14] The existence of a Schauder basis in C 1 ([0, 1] 2) was a question from Banach ...
That is, if M is the square matrix of an endomorphism of V over an "old" basis, and P is a change-of-basis matrix, then the matrix of the endomorphism on the "new" basis is P − 1 M P . {\displaystyle P^{-1}MP.}
