ABSTRACT In this paper, we study some families of right modules of quaternionic slice regular functions induced by a generalized fractal–fractional derivative with respect to a truncated quaternionic exponential function on slices. Important Banach spaces of slice regular functions, namely, the Bergman and the Dirichlet modules, are two important elements of one of our families.
González‐Cervantes et al. (Wed,) studied this question.
