In these notes, we investigate the tail behaviour of the norm of subgaussian vectors in a Hilbert space. The subgaussian variance proxy is given as a trace class operator, allowing for a precise control of the moments along each dimension of the space. This leads to useful extensions and analogues of known Hoeffding-type inequalities and deviation bounds for positive random quadratic forms. We give a straightforward application in terms of a variance bound for the regularisation of statistical inverse problems.

  1. Quantitative Propagation of Chaos and Fluctuations for Kinetic McKean--Vlasov SDEs with Singular Interaction Kernels

    math.PR 2026-07 accept novelty 7.0

    Kinetic McKean–Vlasov systems with singular Kato-class kernels enjoy path-space entropy chaos at rate k/N and a Gaussian fluctuation CLT with N^{-1/6} Berry–Esseen projections.
