摘要
讨论可加稳定分量过程局部时的存在性和连续性,证明了在N>max1≤k≤N∑hl=1dlαlk条件下,N指标可加稳定分量过程X={X(t);t∈RN+}a.s.存在关于时间变量t和空间变量x联合连续的局部时.
The existence of jointly continuous local times of multiparameter processes with additive stable components are discussed.If N>(max)1≤k≤N∑hl=1d_lα_(lk),then the N-parameter process with additive stable components admits jointly continuous local times.
