A reviewer noted "a pleasing feature is the frequent reference to the history of the subject", and "the authors pursue the theory in great detail, proving a large number of subsidiary results.
[citation needed] Rajagopal conducted research on sequences, series, summability, and published more than 80 papers but is most noted for his work in the area of generalising and unifying Tauberian theorems.
[citation needed] Rajagopal also conducted research in the history of medieval Indian mathematics.
