    Published 2024-03-01
    “…The kinematic constraint variation relation of a closed-loop system is built in matrix and vector space with Lie group and Lie algebra theory respectively. The results indicate that the attitude variation between the driven body and the follower body has a linear recursion relation, which is the basis for dynamics modelling. …”

The finite (i.e.,finitely generated over H) simple Lie pseudoalgebras were classified in our previous work (Bakalov etal., 2001) [2] . …”

    The coupling flow of N $$ \mathcal{N} $$ = 4 super Yang-Mills theory by Maximilian Rupprecht

    Published 2022-04-01
    “…We propose a general theory of the N $$ \mathcal{N} $$ = 4 coupling flow operator, arguing that it exhibits an ambiguity in form of an R-symmetry freedom given by the Lie algebra su $$ \mathfrak{su} $$ (4). This theory incorporates our two construction approaches as special points in su $$ \mathfrak{su} $$ (4) and defines a broad class of Nicolai maps for N $$ \mathcal{N} $$ = 4 SYM.…”

    The role of positivity and causality in interactions involving higher spin by Bert Schroer

    Published 2019-04-01
    “…These principles (and not the imposed gauge symmetry) account also for the Lie-algebra structure of the leading contributions of selfinteracting vector mesons.Second order consistency of selfinteracting vector mesons in SLFT requires the presence of H-particles; this, and not SSB, is the raison d'être for H.The basic conceptual and calculational tool of SLFT is the S-matrix. …”
