Let, for each , (, ۔) be a random measure on the Borel -algebra in ℝ such that E(, ℝ) < ∞ for all and let ψ ^ (, ۔) be its characteristic function. We call the function ψ ^ ( ,…, ; ,…, ) = 𝖤 ∏ j = 1 l ψ ^ ( t j , z j ) of arguments ℕ, , … , , ℝ the of the measure-valued random function (MVRF) (۔, ۔). A...

We present a basic althought little known numerical stability condition: for convection equations, the von Neumann stability constraint ∥ ∥ ≤ (1 +    Δ) ∥ ∥ drives to the stability condition Δ ≤ Δ with α = p ( 2 q − 1 ) q ( 2 p − 1 ) where is an integer linked to the stability domain of the time scheme and  ≥  an integer linked to the upwind property of the space discretization...
