The Manchester Numerical Linear Algebra group was very active in 2014. This post summarizes what we got up to. Publications are not included here, but many of them can be found on MIMS EPrints under the category Numerical Analysis.
A new venture for several of us this year was to make our software available on GitHub: Deadman, Higham, Relton, Sego, Zhang.
Three students successfully defended their theses:
- Ramaseshan Kannan, Numerical Linear Algebra Problems in Structural Analysis, Ph.D., University of Manchester, October 2014, 143 pp.
- Samuel D. Relton, Algorithms for Matrix Functions, their Fréchet Derivatives, and Condition Numbers, Ph.D., University of Manchester, November 2014, 146 pp.
- Leo Taslaman, Algorithms and Theory for Polynomial Eigenproblems, Ph.D., University of Manchester, December 2014, 153 pp.
Sam and Leo are now postdoctoral Research Associates in the group. Ramaseshan is a Senior Engineer at Arup, working in the Manchester office.
Weijian Zhang joined the group in September as a PhD student working with Nick Higham.
Sam Relton and Mary Aprahamian served as President and Treasurer, respectively, of the Manchester SIAM Student Chapter.
