We introduce a new concept of statistical solution in the framework of weak solutions to the barotropic Navier–Stokes system with inhomogeneous boundary conditions. Statistical solution is a family {Mt}t≥0 of Markov operators on the set of probability measures P[D] on the data space D containing the initial data [ϱ, m] and the boundary data dB.{Mt}t≥0 possesses a.a. semigroup property, (Formula presented.){Mt}t≥0 is deterministic when restricted to deterministic data, specifically (Formula presented.) where [ϱ, m] is a finite energy weak solution of the Navier–Stokes system corresponding to the data [ϱ, m, dB] ∈ D.Mt: P[D] → P[D] is continuous in a suitable Bregman–Wasserstein metric at measures supported by the data giving rise to regular solutions.
