Linear Algebra Done Right, Second Edition
... C is called a complex vector space. Usually the choice of F is either obvious from the context or irrelevant, and thus we often assume that F is lurking in the background without specifically mentioning it. Elements of a vector space are called vectors or points. This geometric language sometimes aid ...

Convex Programming - Santa Fe Institute
... A subset C of a Euclidean space is convex if it contains the line segment connecting any two of its members. That is, if x and y are vectors in C and t is a number between 0 and 1, the vector tx + (1 − t)y is also in C. A linear combination with non-negative weights which sum to 1 is a convex combin ...

Since a Banach space X is a vector space, it must possess a Hamel, or vector space, basis, i.e., a subset {xγ }γ∈Γ whose finite linear span is all of X and which has the property that every finite subcollection is linearly independent. Any element x ∈ X can therefore be written as some finite linear ...

Lp space
In mathematics, the Lp spaces are function spaces defined using a natural generalization of the p-norm for finite-dimensional vector spaces. They are sometimes called Lebesgue spaces, named after Henri Lebesgue (Dunford & Schwartz 1958, III.3), although according to the Bourbaki group (Bourbaki 1987) they were first introduced by Frigyes Riesz (Riesz 1910).Lp spaces form an important class of Banach spaces in functional analysis, and of topological vector spaces.Lebesgue spaces have applications in physics, statistics, finance, engineering, and other disciplines.
