    Geometric Aspects of the Isentropic Liquid Dynamics and Vorticity Invariants by Alexander A. Balinsky, Denis Blackmore, Radosław Kycia, Anatolij K. Prykarpatski

    Published 2020-10-01
    “…We analyze the adiabatic liquid dynamics, within which, following the general approach, the nature of the related Poissonian structure on the fluid motion phase space as a semidirect Banach groups product, and a natural reduction of the canonical symplectic structure on its cotangent space to the classical Lie-Poisson bracket on the adjoint space to the corresponding semidirect Lie algebras product are explained in detail. We also present a modification of the Hamiltonian analysis in case of a flow governed by isothermal liquid dynamics. …”

    On a class of conformal E $$ \mathcal{E} $$ -models and their chiral Poisson algebras by Sylvain Lacroix

    Published 2023-06-01
    “…The case of degenerate E $$ \mathcal{E} $$ -models, in which a subalgebra of the current algebra is gauged, is more involved: the conformal condition yields a wider class of theories, which includes gauged WZW models but also other examples, seemingly different, which however sometimes turn out to be related to gauged WZW models based on other Lie algebras. For this class, we build non-local chiral fields of parafermionic-type as well as higher-spin local ones, forming classical W $$ \mathcal{W} $$ -algebras. …”

    Quantum robust control theory for Hamiltonian and control field uncertainty by Andrew Koswara, Vaibhav Bhutoria, Raj Chakrabarti

    Published 2021-01-01
    “…To provide guidelines as to the types of quantum control systems and control objectives for which asymptotic robustness analysis is important for accuracy, we introduce methods for assessing the Lie algebraic depth of quantum control systems, and illustrate through examples drawn from quantum information processing how such accurate methods for quantification of robustness to noise and uncertainty are more important for control strategies that exploit higher order quantum pathways. …”

    Addendum to “Quantum deformations of D=4 Euclidean, Lorentz, Kleinian and quaternionic o⋆(4) symmetries in unified o(4;C) setting” [Phys. Lett. B 754 (2016) 176–181] by Andrzej Borowiec, Jerzy Lukierski, Valeriy N. Tolstoy

    Published 2017-07-01
    “…Applying reality conditions to the complex o(4;C) r-matrices we obtained the nonisomorphic classical r-matrices for all possible real forms of o(4;C): Euclidean o(4), Lorentz o(3,1), Kleinian o(2,2) and quaternionic o⋆(4) Lie algebras. In the case of o(4) and o(3,1) real symmetries these r-matrices give the full classifications of the inequivalent quasitriangular quantum deformations, however for o(2,2) and o⋆(4) the classifications are not full. …”
