Vlll PREFACE kind (integration); (vii) in association with related external communities (Vpspaces); (viii) and its behaviour in external environment (range); (ix) in its internal environment (lifting). Measure Theory (The Study of Countably Additive Measures) is an integral part of this wider study and the contrast between finite additivity and countable additivity is brought into sharp focus at various junctures in this work. This book contains a good number of examples illustrating various aspects of finitely additive measures. A special feature of this book is the Selected Annotated Bibliography provided at the end of the book listing research papers we have come across in our pursuit of finitely additive measures. We hope that this book serves practising analysts well and stimulates further research. K.P.S. Bhaskara Rao gave a series of lectures on some of the topics covered in this book at the University of Lecce (Italy) in 1980 and at the University of Naples in 1981. He acknowledges gratefully the help given by these universities in making the visits possible. We also thank the Indian Statistical Institute for rendering help in making reciprocal visits of the authors possible in connection with this work. Finally, a word of appreciation and gratitude to Surekha for her monumental patience in putting up with one of the most taxing and demanding spouses while this work was in progress. We also thank B. R. Marepalli for typing the entire manuscript.
