1. Introduction

Noor Muhammad (15 April 1951 – 12 April 2004) was a notable Pakistani mathematician and mathematics writer who made an original contribution to the fields of C*-algebra, symmetric topology and pure mathematics.Cite error: Closing </ref> missing for <ref> tag

2. International Centre for Theoretical Physics

Noor Muhammad joined International Centre for Theoretical Physics on the request of prominent theoretical physics and nobel laureate in Physics Dr. Prof. Abdus Salam. As a post-doctoral fellow, he also worked on P-Commutative Topological Algebras. From 1990 until 1995, he became an associate member of mathematician at ICTP. Noor Mohammad, at ICTP, published more than 30 articles in refereed international journals during the course of his career.^[1]

3. Academic Career in Mathematics

He reluctantly returned to Pakistan where he joined Quaid-i-Azam University and became a chairperson of the Department of Mathematics. he produced a number of research papers on elliptic pseudo-differential operators over C*-algebras for compact manifold. He had also published papers on topics in approximation theory, derivation on topological algebras and multipliers of topological algebra.

In mathematics, functional analysis depends heavily upon topology, especially the branch of Functional Analysis that Dr. Noor Muhammad specialised in. His lectures notes on a first course on functional analysis, a copy of which is still available, are topological based. He was a close associate and colleague of dr. Qaiser Mushtaq, and had cordial relationship with him. In 2000, Dr. Noor Muhammad began to write college-level textbook on topology, however, after his death, the book is remained incompleted.

4. Death

In 2003, Dr. Noor Muhammad, was diagnosed with a heart ailment. Soon after, he had heart surgery, which he barely survived. His friends and colleagues in the Department of Mathematics advised him to take at least a semester off. Dr. Qaiser Mushtaq, who became a new head of the department, managed to arrange a substitute professor Dr. Akbar Azam, who was then teaching at the Government College University.

After about a semester's respite, Dr Noor Muhammad restarted lecturing in the department. He regularly attended the meetings.

According to the Dr. Qaisar Mustaq's memoir, Dr. Noor Muhammad was very tense in the PhD Committee Meeting that he attended one day before he died. Dr Noor Muhammad could not take the pressure any more and asked for leave half way through.

Next morning, he was pronounced dead. He did not live to marry off his daughter, enjoy driving in his newly bought Toyota car, and publish his book on topology. His death has deprived the Mathematics Department, Quaid-i-Azam University, of its sole Functional Analyst.
