摘要

This paper investigates operators formed by the iteration of two Volterra-type operators. The kernels involved satisfy general conditions that extend previous results in Stepanov and Shambilova (Math Inequal Appl 22(4):1505–1533, 2019. https://doi.org/10.7153/mia-2019-22-105), which were established for kernels satisfying the Oinarov condition. Necessary and sufficient conditions are established for the boundedness of these iterated operators between weighted Lebesgue spaces.
