Что (кто) такое uniformly convex - определение
Uniformly convex space
REFLEXIVE BANACH SPACE SUCH THAT THE CENTER OF A LINE SEGMENT INSIDE THE UNIT BALL MUST LIE DEEP INSIDE THE UNIT BALL UNLESS THE SEGMENT IS SHORT
Uniformly convex Banach space; Uniformly convex banach space; Uniform Convexity; Uniform convexity; Uniformly convex
In mathematics, uniformly convex spaces (or uniformly rotund spaces) are common examples of reflexive Banach spaces. The concept of uniform convexity was first introduced by James A.

<mathematics, graphics> For a set S in space, the smallest
convex set containing S. In the plane, the convex hull can
be visualized as the shape assumed by a rubber band that has
been stretched around the set S and released to conform as
closely as possible to S.

NOTION IN TOPOLOGICAL VECTOR SPACES
Convex envelope; Closed convex hull; Convex Hull; Convex span; Convex closure; Minimum convex polygon; Applications of convex hulls
In geometry, the convex hull or convex envelope or convex closure of a shape is the smallest convex set that contains it. The convex hull may be defined either as the intersection of all convex sets containing a given subset of a Euclidean space, or equivalently as the set of all convex combinations of points in the subset.
