In this paper, we first establish the conditions for a sequence to become a wrts-Cauchy and wrtn-Cauchy sequence in cone A-b-metric spaces. Next, we prove fixed point theorems with operator coefficients in cone A-b-metric spaces. We also give an example to show that known results in the literature are not applicable while our result is. Finally, we provide two applications of the results.
