  text: In this paper we consider a class of stochastic reaction-diffusion equations.
    We provide local well-posedness, regularity, blow-up criteria and positivity of
    solutions. The key novelties of this work are related to the use transport noise,
    critical spaces and the proof of higher order regularity of solutions – even in
    case of non-smooth initial data. Crucial tools are Lp(Lp)-theory, maximal regularity
    estimates and sharp blow-up criteria. We view the results of this paper as a general
    toolbox for establishing global well-posedness for a large class of reaction-diffusion
    systems of practical interest, of which many are completely open. In our follow-up
    work [8], the results of this paper are applied in the specific cases of the Lotka-Volterra
    equations and the Brusselator model.

  text: A stochastic PDE, describing mesoscopic fluctuations in systems of weakly
    interacting inertial particles of finite volume, is proposed and analysed in any
    finite dimension . It is a regularised and inertial version of the Dean–Kawasaki
    model. A high-probability well-posedness theory for this model is developed. This
    theory improves significantly on the spatial scaling restrictions imposed in an
    earlier work of the same authors, which applied only to significantly larger particles
    in one dimension. The well-posedness theory now applies in d-dimensions when the
    particle-width ϵ is proportional to  for  and N is the number of particles. This
    scaling is optimal in a certain Sobolev norm. Key tools of the analysis are fractional
    Sobolev spaces, sharp bounds on Bessel functions, separability of the regularisation
    in the d-spatial dimensions, and use of the Faà di Bruno's formula.
