We present the expansion of the multifractional Brownian (mBm) local time inhigher dimensions, in terms of Wick powers of white noises (or multiple Wienerintegrals). If a suitable number of kernels is subtracted, they exist in thesense of generalized white noise functionals. Moreover we show the convergenceof the regularized truncated local times for mBm in the sense of Hidadistributions.
