Professor Beg roles as teacher and mentor are also exceptional, and are felt
well beyond national boundaries. He has promoted the cause of mathematics in
general and of functional analysis in particular by organizing series of
symposia and conferences both national and regional. He is also member of board
of studies of several universities. He is member of Editorial Board of twelve
international journals. He is also a reviewer of Zentralblatt Fur Mathematik
(Germany), Mathematical Review (USA) and The Natural Sciences and Engineering
Research Council of Canada. Dr. Beg is a member of European Mathematical
Society, American Mathematical Society, International Federation of Nonlinear
Analysts, International Rough Set Society, Society for Mathematics of
Uncertainty, All Pakistan Mathematical Association and Punjab Mathematical
Society.
