Unicity for representations of the Kauffman bracket skein algebra [PDF]
Inventiones Mathematicae, 2017 This paper resolves the unicity conjecture of Bonahon and Wong for the Kauffman bracket skein algebras of all oriented finite type surfaces at all roots of unity.

Evaluation of the Effects of Different Mouthrinses on the Color Stability of One Type of Glass Ionomer, Compomer and Giomer [PDF]
Journal of Dental Materials and Techniques, 2016 Objectives: The aim of this study was to evaluate the effect of four commercially available mouthrinses on the color stability of one type of glass ionomer, giomer and compomer. Method: 60 disc-shaped specimens, 180 in total (7*2mm), fabricated from each

Courant bracket found out to be T-dual to Roytenberg bracket [PDF]
The European Physical Journal C, 2020 AbstractBosonic string moving in coordinate dependent background fields is considered. We calculate the generalized currents Poisson bracket algebra and find that it gives rise to the Courant bracket, twisted by a 2-form $$2B_{\mu \nu }$$2Bμν. Furthermore, we consider the T-dual generalized currents and obtain their Poisson bracket algebra.

International Journal of Geometric Methods in Modern Physics, 2013 We review origins and main properties of the most important bracket operations appearing canonically in differential geometry and mathematical physics in the classical, as well as in the supergeometric setting. The review is supplemented by some new concepts and examples.

Topology and its Applications, 2020 We introduce \textit{Kaestner brackets}, a generalization of biquandle brackets to the case of parity biquandles. This infinite set of quantum enhancements of the biquandle counting invariant for oriented virtual knots and links includes the classical quantum invariants, the quandle and biquandle $2$-cocycle invariants and the classical biquandle ...

The Moyal bracket and the dispersionless limit of the KP hierarchy [PDF]
, 1994 A new Lax equation is introduced for the KP hierarchy which avoids the use of pseudo-differential operators, as used in the Sato approach. This Lax equation is closer to that used in the study of the dispersionless KP hierarchy, and is obtained by ...
