设(T,θ,dt)是具有非原子测度dt的可测空间.设X是完备可分度量空间.设U(X,t)是从X × T到实数R的函数,设gi(x,t),.,g,(x,t)是从X × T到[0,ω]的函数。令c+,…,01,是正的真实的数。我们写g=(g,,...,gn)和a=(ai,...,an)。问题~ P(u,g,a)如下:
Let (T, 9, dt) be a measurable space with a nonatomic measure dt. Let X be a complete separable metric space. Let U (X, t) be a function from X x T into the reals R, and let gi (x, t),..., g,(x, t) be functions from X x T into [0, co]. Let c+,..., 01, be positive real numbers. We write g=(g,,..., gn) and a=(ai,..., an). The problem~ P (u, g, a) is as follows:
