Essay

We construct the sets of stability to perturbations of infinite branched continued fractions (BCF) with positive elements. We investigate the stability to perturbations of BCF with real elements, in particular, with the negative and alternating elements, as well as some subsequences of their approximants. We construct the sets of stability to perturbations, in particular, the multidimensional sets, of BCF of the general and special form with complex elements. We establish the estimates errors of approximants of BCF.
