Modern Analysis comprises the fields of Topology, Functional Analysis, Operator Theory, Harmonic Analysis, Theory of Lie Groups, Fractional Calculus, Measure Theory, etc. The last two decades have seen rapid advances in these areas influencing extensively the entire gamut of mathematics. Most of these fields are being usefully employed not only in many other areas of mathematics but also in various physical theories and problems. To instill better awareness of the recent developments, the Department of Mathematics, Indian Institute of Technology, New Delhi, organized a symposium in December 1983 with the participation of eminent mathematicians from several countries.
