https://doi.org/10.1007/978-981-19-4250-1In this chapter, we recall the notion of almost convergence and statistical convergence for single sequences .=(..). We present here a brief survey on developments of almost convergence, statistical convergence, and some related methods, e.g., absolute almost convergence and strong almost convergence for single sequences.
