The Poisson and graded Poisson Schouten–Nijenhuis algebras of symmetric and antisymmetric contravariant tensor fields, respectively, on an n-dimensional manifold M are shown to be n-symplectic. This is accomplished by showing that both brackets may be defined in a unified way using the n-symplectic structure on the bundle of linear frames LM of M.

The present invention concerns a bracket (1) having a body (2 A) that defines a base (2); a slot (5) formed in said body and designed to accommodate an orthodontic archwire (4), a plurality of wings (3) formed in said body; a plurality of seats (12, 12') formed on one or more of said plurality of wings, each seat defining a bottom (13, 13') and at ...

An antichain is associated to each link diagram so that the highest degree of the Kauffman bracket can be determined. As an application, we show that the span of the Kauffman bracket is less than or equal to 4(n - m) for dealternator connected m-alternating diagrams and the upper bound is best possible.

To achieve orthodontic tooth movement, archwires must be tied to the bracket slots. Metal or elastic ligatures are used for this purpose, and the way they are tied affects tooth movement. Because of their design, twin brackets can be tied in a large variety of ways.

Abstract Brackets can add clarity and simplicity because they help writers avoid shoving an ill-fitting quote into their writing. All the justices use brackets when part of a quote doesn’t quite work, making these sharp parenthetical marks a key part of the legal writer’s toolkit.
