Girth (tack) Girth (tack) A girth, sometimes called a cinch (Western riding), is a piece of equipment used to keep the saddle in place on a horse or other animal. It passes under the barrel of the equine, usually attached to the saddle on both sides by two or three leather straps called billets. Girths are used on Australian and English saddles, while western saddles and many pack saddles have a cinch, which is fastened to the saddle by a single wide leather strap on each side, called a latigo. Although a girth is often enough to keep a well-fitting saddle in
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
