考虑欧几里德空间上的一类均匀椭圆扩散过程。我们对起始点统一地估计跃迁密度和它们的导数。我们用这些结果证明了在一定条件下∇P c t的遍历性(见(1.2)和定理1.4)。这对于大偏差原理的精确估计是有用的。
Consider a class of uniform elliptic diffusion processes on Euclidean spaces. We estimate transition densities and their deriva- tives uniformly with respect to the starting points. We use these re- sults to prove an ergodicity of ∇P c t (see (1.2) and Theorem 1.4) under certain conditions. This is useful in precise estimate of large deviation principles.
