Ismat Beg (Urdu: عصمت بیگ; born January 1951) is a Pakistani mathematician and academic. He serves as Distinguished National Professor at the Lahore School of Economics and has held faculty positions at universities in Pakistan and abroad. His research contributions span fixed point theory, fuzzy sets, order structures, artificial intelligence, and multicriteria decision-making.

Early life and education

Beg was born in January 1951 in Mohri Sharif, a village near Kharian, to a Kashmiri immigrant family. He attended Sapper Boys High School in Risalpur and later studied at Zamindar College in Gujrat. He earned his master's degree in mathematics from Government College University (Lahore). In 1977, he traveled to Romania, where he completed pre-doctoral studies at the West University of Timișoara and obtained his Ph.D. in mathematics from the University of Bucharest in 1982 under the supervision of Romulus Cristescu. His doctoral research focused on ordered vector spaces and integral representation of linear operators.

Academic career

Beg began his academic career after completing his Ph.D. in 1982. He has taught at several institutions, including Lahore School of Economics, Lahore University of Management Sciences, Quaid-i-Azam University, University of Central Punjab, and Kuwait University. He has also been affiliated with international institutions such as the International Centre for Theoretical Physics in Trieste, Italy, and Nankai University in China.

His interdisciplinary research covers mathematics, computer science, economics, and decision theory. He has published extensively in peer-reviewed journals and has been cited widely in the academic literature. He has supervised doctoral and postdoctoral research and serves on editorial boards of multiple academic journals, including the Proceedings of the Pakistan Academy of Sciences and Journal of Function Spaces.

Beg was recognized as a Distinguished National Professor by the Higher Education Commission (Pakistan). He was awarded a Gold Medal by the Pakistan Academy of Sciences in 2008 and received the National Book Council of Pakistan Prize in 1986. From 1990 to 2010, he held various research positions at the International Centre for Theoretical Physics.

Professional affiliations

Beg is a fellow of the Pakistan Academy of Sciences and the Institute of Mathematics and its Applications. He is also affiliated with the London Mathematical Society, the American Mathematical Society, and the European Mathematical Society. He holds the title of Chartered Mathematician and is a member of the European Society for Fuzzy Logic and Technology.
