Abstract:We study a family of Brascamp-Lieb forms acting on families of weighted $ L^p$-spaces and Lorentz spaces where the weight is a power of the distance to the origin. We establish a set of necessary conditions and a set of sufficient conditions for the finiteness of these forms in Lorentz spaces. The conditions are close to optimal.

具有幂权重的𝐿^ {power}-空间中Brascamp-Lieb形式的估计

摘要:我们研究了作用于加权$ L ^ p $空间和洛伦兹空间族的一类Brascamp-Lieb形式,其中权重是距离原点的距离的幂。我们为洛伦兹空间中这些形式的有限性建立了一组必要条件和一组充分条件。条件接近最佳。
