Introduction

Introduction | Nodes | Scientific Committee | Meetings | Publications |Software

 

MOPNET is an EPSRC Network to study the linear algebra, analysis, engineering and physics of matrix and operator pencils. The Network started officially on 1st July 2009, although there was a Meeting Zero from March 30th-31st 2009, financed by Cardiff School of Mathematics and the Wales Institute for Mathematical and Computational Sciences.

The main research topics covered by MOPNET will be:

• General theory of operator pencils;
• Theory and numerics for structured polynomial problems;
• Numerical methods for spectra of analytic pencil problems;
• Pseudospectra of analytic functions;
• Linear algebra of structured parameter-dependent linear systems;
• PDEs on domains with special structure.

1. MOPNET is genuinely interdisciplinary, bringing together engineers, mathematicians and physicists to speak and work on problems of mutual interest.


NEXT MEETING: 2-3 April 2012 in BATH. Details here.
