Derivation of reduced two-dimensional fluid models via Dirac's theory of constrained Hamiltonian systems [PDF]
, 2010 We present a Hamiltonian derivation of a class of reduced plasma two-dimensional fluid models, an example being the Charney-Hasegawa-Mima equation. These models are obtained from the same parent Hamiltonian model, which consists of the ion momentum ...

On the Quantization of Poisson Brackets [PDF]
Advances in Mathematics, 1997 In this paper we introduce two classes of Poisson brackets on algebras (or on sheaves of algebras). We call them locally free and nonsingular Poisson brackets. Using the Fedosov's method we prove that any locally free nonsingular Poisson bracket can be quantized.

The results of clinical testing of photodynamic therapy in the complex treatment of gingivitis, complicating orthodontic treatment with bracket systems. [PDF]
Medičnì Perspektivi, 2016 In spite ofa high efficiency, the use of brackets in orthodontic patients can provoke the development of inflammatory processes in marginal periodontal tissues.

Exterior Differentials in Superspace and Poisson Brackets
, 2003 It is shown that two definitions for an exterior differential in superspace, giving the same exterior calculus, yet lead to different results when applied to the Poisson bracket.

Supersymmetry and the Odd Poisson Bracket [PDF]
, 2002 Some applications of the odd Poisson bracket developed by Kharkov's theorists are represented, including the reformulation of classical Hamiltonian dynamics, the description of hydrodynamics as a Hamilton system by means of the odd bracket and the ...

Prospects of the Nambu bracket [PDF]
Progress of Theoretical and Experimental Physics, 2016 We review recent progress in formulating the worldvolume theory of M2-branes using the Nambu bracket. Although it is generally agreed that this formulation should be replaced by another using the superconformal Chern-Simons theory, we try to pursue a possible complementary role played by the Nambu bracket.
