ATM Schools:  Matrix Theory, Panjab University, Chandigarh, Application Deadline: November 18, 2023

The Advanced Training in Mathematics Schools (ATM Schools) were launched by the National Board for Higher Mathematics (NBHM) in May 2004. The purpose of these schools is to provide training in core subjects in Mathematics to Ph.D. students, young researchers and teachers. The emphasis in these schools is on learning mathematics by doing it. IIT Bombay and TIFR have jointly established the National Centre for Mathematics (NCM) in 2011. The instructional schools and workshops which were earlier planned by an NBHM committee on ATM Schools are now being organized under the supervision of the Apex Committee of the NCM.

Matrix theory is a fundamental branch of mathematics having incredibly diverse and far-reaching applications in various fields, including engineering, statistics, computer science, and finance. Its use is critical to many areas of modern science and technology.
The workshop on matrix theory will feature three mini courses from some prominent mathematicians and leading experts in the area. This one-week long event will focus on various aspects of matrix theory, and its connections with Fourier analysis, real and complex analysis and numerical linear algebra to solve problems related to matrices, matrix factorizations and their applications, and the theory of functions that preserve matrix positivity. The programme is aimed at Ph.D. students, post-doctoral fellows and researchers interested in matrix theory and related areas.

Dates: 18 Dec 2023 to 23 Dec 2023
