statistical deferred weighted riemann summability and fuzzy approximation theorems

The notion of statistical convergence has fascinated many researchers due mainly to the fact that it is more general than the well-established hypothesis of ordinary (classical) convergence. this work aims to investigate and present (presumably new) the statistical versions of deferred weighted riemann integrability and deferred weighted riemann summability for sequences of fuzzy functions. we first interrelate these two lovely theoretical notions by establishing an inclusion theorem. we then state and prove two fuzzy korovkin-type theorems based on our proposed helpful and potential notions. we also demonstrate that our results are the nontrivial extensions of several known fuzzy korovkin-type approximation theorems given in earlier works. moreover, we estimate the statistically deferred weighted riemann summability rate supported by another promising new result. finally, we consider several interesting exceptional cases and illustrative examples supporting our definitions and the results presented in this paper.
