Stable belt Stable belt A stable belt is an item of uniform used in the armed forces of Denmark, the United Kingdom and other Commonwealth countries. Gymnastic belts are similar coloured belts used in Brazil and Lebanon. The stable belt originates from when cavalrymen would place the surcingle around the waist when cleaning the stables and tending to their horses. In the 1950s they spread to all branches of the armed forces, adding a splash of colour and individuality to the drab khaki working uniforms. Initially they were resisted by many senior officers, who saw them as too individualistic, but they soon
Girth (functional analysis) within the sphere that they do in the whole space. The girth is a continuous function on the Banach–Mazur compactum, a space whose points correspond to the normed vector spaces of a given dimension. The girth of the dual space of a normed vector space is always equal to the girth of the original space. Girth (functional analysis) In functional analysis, the girth of a Banach space is the infimum of lengths of centrally symmetric simple closed curves in the unit sphere of the space. Equivalently, it is twice the infimum of distances between opposite points of the sphere, as
