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]
