    Global gross primary production from vegetation photosynthesis model for 2017-2019 (2021)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: This dataset contains 8-day temporal resolution, 500m spatial resolution gross primary production (GPP) estimation from vegetation photosynthesis model (VPM) for the entire globe during 2017-2019. The entire globe is divided into 290 sub area (tiles) under a sinusoidal projection. For each tile each year, there are 46 GeoTiff files, each one represents the average daily GPP during a 8-day period. Each GPP file is also associated with a quality control layer, which contains a Boolean value to indicate whether the data quality is good (0) or not (1). The simulated GPP is also validated against 113 eddy covariance flux tower across the globe.

    Affine Yang-Mills theory and affine self-dual Chern-Simons Solitons (1992)

    Notizen: Abstract A four-dimensional affine Yang-Mills theory, i.e. Yang—Mills gauge theory with values in an affine Kac-Moody algebra, is constructed which can give rise to a spontaneous breakdown of the affine symmetry. The affine self-dual Yang-Mills equation (which is a special kind of affine YM theory) in four dimensions is dimensionally reduced to the affine self-dual Chem-Simons equation in two dimensions. The latter is shown to have soliton solutions which satisfy the conformal affine Toda equations.

    Loop Group-Valued CS and WZNW models, integrable systems, and self-dual Yang-Mills theory (1992)

    Notizen: Abstract Affine CS and WZNW theories with values in infinite-dimensional (loop) groups are proposed. It appears that the affine CS theory naturally introduces a spectral parameter into a CS theory. The Sinh-Gordon, KdV, and nonlinear Schrödinger equations are obtained, via Hamiltonian reductions, from the affine WZNW. It is shown that the self-dual Yang-Mills (SDYM) equation is related to the equation of motion of the affine WZNW and, thus, symmetry algebra underlying the SDYM can be identified with the affine two-loop Kac-Moody algebra of the affine WZNW.

    Quantum affine algebras and universalR-matrix with spectral parameter (1994)
    Springer
    Letters in mathematical physics 31 (1994), S. 101-110

    Notizen: Abstract Using the previously obtained universalR-matrix for the quantized nontwisted affine Lie algebras U q (A 1 (1) ) and U q (A 2 (1) ), we determine the explicitly spectral dependent universalR-matrix for the corresponding quantum Lie algebras U q (A 1) and U q (A 2). As applications, we reproduce the well known results in the fundamental representations and we also derive an extremely explicit formula of the spectral-dependentR-matrix for the adjoint representation of U q (A 2), the simplest nontrivial case when the tensor product decomposition of the representation with itself has nontrivial multiplicity.
