Gene Golub SIAM Summer School 2013

A two week Gene Golub SIAM summer school on matrix functions and matrix equations was held at Fudan University, Shanghai from July 22 to August 2, 2013, in conjunction with the 3rd International Summer School on Numerical Linear Algebra and the 9th Shanghai Summer School on Analysis and Numerics in Modern Sciences. This was the fourth Golub Summer School and the second devoted to numerical linear algebra.

45 PhD students attended, coming from institutions in 15 countries. The lecturers were me and Marlis Hochbruck (Karlsruhe Institute of Technology, Germany) in week 1 and Peter Benner (Max Planck Institute, Magdeburg), Ren-Cang Li (University of Texas, Arlington) and Xiaoye (Sherry) Li (Lawrence Berkeley National Laboratory, USA) in week 2.

My 10 hours of lectures were on matrix functions. The slides and exercises can be downloaded from my website.

The lectures were held in the mornings in the GuangHua Twin Tower – an impressive, marbled 30-storey building on the Fudan campus. Attendees were grateful that the lecture room was air conditioned, as the Shanghai summer was at its peak of temperature and humidity, and on the Friday of the first week a record temperature of 40.6 degrees Celsius (105 degrees Fahrenheit) was reached in the city.

Afternoons contained exercise sessions, 10-minute presentations by the students on their thesis work, and a guest seminar by Hongguo Xu (University of Kansas) in week 1 and Heike Fassbender (TU Braunschweig) in week 2. These were fully attended and it was great to see the students working so enthusiastically together and interacting with the lecturers.

For the lunches and dinners the students and lecturers sat together in randomized positions – an excellent idea on the part of the local organizers which helped ensure that people got to know each other.

Group photos at conferences can be rather shambolic. This one was the most professional I’ve ever seen. When we arrived at the designated spot the photographer had already set up three rows of metal staging and the photo was quickly taken (just as well given the scorching heat even at 8.15 am). Laminated photos were delivered to participants the same afternoon.

The local organizers are to be congratulated on an excellent job. In particular, Weiguo Gao and Yangfeng Su (Fudan University) and Zhaojun Bai (UC Davis) were busy every day making sure that the event ran smoothly. Daniel Szyld (Temple University) must also be mentioned for his excellent work over the last 5 years in chairing the SIAM committee that manages the Gene Golub SIAM Summer School program.

The school was generously supported by the SIAM Gene Golub Summer School fund, the Shanghai Center for the Mathematical Sciences, ISFMA (Sino French Institute of Applied Mathematics), the NSF (USA) and NAG.

Three things will stand out in my memory from the School. First, the enthusiasm of the students, among whom will no doubt be some of the future leaders of our field. (See the blog post by my PhD student Sam Relton.) Second, sitting in the plush 15th floor cafe of the GuangHua Tower chatting to other participants over a cafe latte with smooth jazz coming over the speakers. Third, the Chinese (motor) cyclists, who carry a wondrous variety of goods on their bikes and ride without any attention to the traffic signals but miraculously seem to avoid accidents. See the photos below taken on the short walk from the hotel to the department!

In summing up I can do no better than to endorse Charlie Van Loan’s words in describing the first Gene Golub Summer School in 2010: “The idea of a summer school for graduate students from around the world is the perfect way to honor Gene’s memory. It is exactly the kind of activity that Gene loved to promote.”
