Virtual knots undetected by 1 and 2-strand bracket polynomials [PDF]
, 2004 Kishino's knot is not detected by the fundamental group or the bracket polynomial; these invariants cannot differentiate between Kishino's knot and the unknot.

Correlates of Narrow Bracketing [PDF]
The Scandinavian Journal of Economics, 2019 AbstractBehavior often deviates from standard predictions because individuals evaluate the consequences of choices separately (i.e., narrow bracketing) rather than jointly. The main existing theories classify different narrow bracketing phenomena as either (i) choice errors caused by cognitive limitations, or (ii) strategies to achieve self‐control ...

Journal of Dentistry Indonesia, 2015 The incidence of loose brackets during orthodontic treatment has reached 5%; therefore, loose brackts should be rebonded. Rebonding without etching might decrease chair time without compromising bond strength.

On Field Theoretic Generalizations of a Poisson Algebra [PDF]
, 1997 A few generalizations of a Poisson algebra to field theory canonically formulated in terms of the polymomentum variables are discussed. A graded Poisson bracket on differential forms and an $(n+1)$-ary bracket on functions are considered.

Algebraic string bracket as a Poisson bracket
Journal of Noncommutative Geometry, 2010 In this paper we construct a Lie algebra representation of the algebraic string bracket on negative cyclic cohomology of an associative algebra with appropriate duality. This is a generalized algebraic version of the main theorem of [AZ] which extends Goldman’s results using string topology operations.The main result can be applied to the de Rham ...

Biquandle brackets and knotoids [PDF]
Journal of Knot Theory and Its Ramifications, 2021 Biquandle brackets are a type of quantum enhancement of the biquandle counting invariant for oriented knots and links, defined by a set of skein relations with coefficients which are functions of biquandle colors at a crossing. In this paper, we use biquandle brackets to enhance the biquandle counting matrix invariant defined by the first two authors ...

The Hamiltonian description of incompressible fluid ellipsoids [PDF]
, 2008 We construct the noncanonical Poisson bracket associated with the phase space of first order moments of the velocity field and quadratic moments of the density of a fluid with a free- boundary, constrained by the condition of incompressibility.

Letters in Mathematical Physics, 2004 We survey the many instances of derived bracket construction in differential geometry, Lie algebroid and Courant algebroid theories, and their properties. We recall and compare the constructions of Buttin and Vinogradov, and we prove that the Vinogradov bracket is the skew-symmetrization of a derived bracket.
