Arbind Kumar Lal (01-01-1966 to 07-03-2021), Professor, Department of Mathematics and Statistics, IIT Kanpur, left this mortal world after suffering a heart attack while walking to a research discussion with colleagues. Born at Uttara (Madhubani district, Bihar) to Smt Sushila Devi and Shri Lekh Narayan Lal, he completed his schooling from Sainik School, Tilaiyaa in 1983 and then proceeded to obtain BA (Math, Honors; 1983-86) from Hansraj College, Delhi. Following this, he did an M Stat (1986-88) and PhD (1988-93), both from ISI Delhi. After brief stints at TIFR Mumbai and HRI Allahabad, Arbind joined IIT Kanpur as a faculty in the Department of Mathematics (since renamed as Department of Mathematics & Statistics), in 1996. That year, he also married the love of his life, Niyati Padhi, with whom he has two children, Ayanesh (born 8th August 2001) and Nilisha (born 7th February, 2003).
Arbind served IIT Kanpur in an exemplary manner till his sudden demise. His research expertise was in areas related to linear algebra, graph theory and combinatorics. He made seminal contributions to algebraic connectivity and distance matrix of graphs and also introduced weakly quasi-threshold graphs. He was deeply committed to mathematics education and conducted several summer schools and workshops across the country for faculty and students alike. His linear algebra notes are widely used and appreciated for their lucid exposition of fundamental concepts. Arbind ably conducted mathematics UG institute core courses for very large classes multiple times and received several Senate commendations for outstanding teaching. In addition to his crystal clear lectures, students universally loved him for his genuine concern and support for their well-being. He also contributed liberally to Institute administration, prominent mentions including Head of the Department (Mathematics and Statistics), Chairman of the Senate Undergraduate Committee, President of the Staff Gymkhana, Games Counsellor, and Vice-chairman, GATE.
Arbind was an embodiment of sportsmanship and excelled as a badminton player. Popularly known as “net Samrat”, his net play and drop shots with pin-point accuracy took the breath away of the best of players. He was a regular sight in the early mornings at the courts, even during the last months before his sudden tragic demise.
Arbind possessed a brilliant intellect that rested on the foundation of a soft, generous and genuine heart. He brought a contagious intensity and passion to all that he did, regardless of whether it was mundane or lofty work. So much so that everyone took it for granted, that if Arbind is doing it, it shall be a job well done. The gentlest of souls with an ever smiling disposition and willingness to help, he treated all as his own and was the epitome of sincere, honest, selfless service to the profession and the society at large. He was accommodating to a fault, both in life as well as in passing away, leaving behind a panorama of cherished memories for all who came in touch with him. The smile, the full hearty laugh along with the words “khush raho”, shall remain etched forever in our memories.
While Arbind may have left this mortal world, his spirit lives on in all beings of goodwill and those who cherish him deep in their hearts. Rest in Peace, dearest Arbind, for you are now the beacon reminding us of all that makes life worth living and dying for.
