Quasi-relative interior

In topology, a branch of mathematics, the quasi-relative interior of a subset of a vector space is a refinement of the concept of the interior. Formally, if is a linear space then the quasi-relative interior of is

where denotes the closure of the conic hull.[1]

Let is a normed vector space, if is a convex finite-dimensional set then such that is the relative interior.[2]
