摘要
In this paper we study convergence results and rate of approximation for a family of linear integral operators of Mellin type in the frame of BV phi (R-+(N)) Here BV phi (R-+(N)) denotes the space of functions with bound phi-variation on R-+(N) defined by means of a concept of multidimensional phi-variation in the sense of Tonelli.
