Abstract. The concepts of multiresolution analysis (MRA) and wavelet have been generalized to a local field $K$ of positive characteristic by using a prime element $\mathfrak p$ of such a field. A MRA is a sequence of closed subspaces of $L^2(K)$ satisfying certain properties. In this paper, we are interested in a nonstationary MRA and related wavelets on local fields of positive characteristic.
