Early life and education

Born in Madras (now Chennai), Agarwal received early schooling that led to higher studies at the University of Delhi and advanced training at the Indian Statistical Institute. He pursued doctoral research during a period when scholars in India often collaborated with peers from United Kingdom and United States, drawing influence from developments at institutions such as Cambridge, Oxford, and Princeton. His formative mentors and contemporaries included figures affiliated with All India Institute of Medical Sciences, Tata Institute of Fundamental Research, and international centers like Institute for Advanced Study and Courant Institute.

Academic career and positions

Agarwal's academic appointments span universities in India and the United States, including tenure-track and visiting positions at the University of Delhi, Florida Institute of Technology, Texas A&M University, and University of Texas at El Paso. He has participated in faculty exchanges with departments at Harvard University, Massachusetts Institute of Technology, Stanford University, and research collaborations involving Max Planck Society, CNRS, and the Chinese Academy of Sciences. His career involved administrative roles comparable to professorships, departmental leadership, and international program direction associated with entities like the International Mathematical Union and Society for Industrial and Applied Mathematics.

Research contributions and publications

Agarwal authored and edited monographs and research articles on nonlinear integral equations, oscillation theory, difference equations, and fractional differential equations. His publications interact with literature by scholars linked to Johns Hopkins University, Imperial College London, University of Cambridge, and ETH Zurich, and are cited alongside works by mathematicians from Princeton University, University of California, Berkeley, and Columbia University. He produced contributions that bridge techniques from operator theory developed at Institute for Advanced Study and methods employed in applied contexts at Los Alamos National Laboratory and Bell Labs. His edited volumes assemble chapters by authors affiliated with Oxford University Press, Springer Science+Business Media, and publishers collaborating with academic presses at Elsevier and Wiley-Blackwell.

Awards and honors

Throughout his career Agarwal received recognition from professional bodies comparable to awards granted by the National Academy of Sciences-type organizations, regional academies such as the Indian Academy of Sciences, and international societies akin to the American Mathematical Society and Royal Society. He presented invited lectures at major gatherings including the International Congress of Mathematicians, conferences organized by the European Mathematical Society, and symposia sponsored by the American Association for the Advancement of Science and the World Congress of Nonlinear Analysts.

Professional memberships and editorial work

Agarwal served on editorial boards and refereed manuscripts for journals and publishers associated with Springer, Elsevier, Wiley, and societies such as the American Mathematical Society and the Society for Industrial and Applied Mathematics. He organized sessions and chaired committees within organizations like the International Mathematical Union, European Mathematical Society, Indian Mathematical Society, and international workshops held at centers including the Banff International Research Station and Quaero Center-style venues. His editorial collaborations involved coordinating special issues with scholars from University of Oxford, Seoul National University, University of Tokyo, and University of Melbourne.

Selected students and mentorship

Agarwal supervised doctoral and postdoctoral researchers who later joined faculties at institutions such as the University of Delhi, University of Mumbai, University of Texas, and universities across Canada, Australia, and Singapore. His mentees have contributed to literature cited alongside work from researchers at Princeton University, Caltech, and Imperial College London, and have held positions within research institutes including the Tata Institute of Fundamental Research and the International Centre for Theoretical Sciences.

Legacy and impact on mathematics

Agarwal's legacy encompasses a corpus of research shaping contemporary study of nonlinear difference and fractional equations, influencing curricula and research programs at departments like those in IISc Bangalore, University of Hyderabad, University of Chicago, and Yale University. His edited volumes and conference proceedings continue to serve as references for investigators at laboratories and centers such as Los Alamos National Laboratory, Sandia National Laboratories, and collaborative groups within the European Research Council framework. The diffusion of his methods is evident in ongoing work across continents, reflected in citations by scholars affiliated with Cambridge University Press, Springer Nature, and major mathematical societies.
