Convergence and Rate of Approximation in BVΦ for a Class of Integral Operators

  • S. Sciamannini
  • G. Vinti


We obtain estimates and convergence results with respect to ϕ-variation in spaces BVΦ for a class of linear integral operators whose kernels satisfy a general homogeneity condition. Rates of approximation are also obtained. As applications, we apply our general theory to the case of Mellin convolution operators, to that one of moment operators and finally to a class of operators of fractional order.
