Summary on Grant Application Form
Results on matrix scaling have a long history and the theory now recognises a number of types of scaling. In this project we are concerned with diagonal scaling of nonnegative matrices whose roots go back to the works of Frobenius. An important feature of this type of scaling is that it preserves cycle products and may therefore be useful in the analysis of a class of combinatorial or combinatorial optimisation problems. The main motivation for this research project is that it has recently been realised that there is a deep relation between matrix scaling and max-algebra. Max-algebra is a relatively young area of research on the boundary between algebra and combinatorics with interesting operational research applications. The Visiting Researcher, Professor Schneider (University of Wisconsin) is a world leafing expert in linear algebra and in particular matrix scaling and the principal investigator has a 25-year experience in max-algebra. Their collaboration is expected to create a passage between these two fields of research which have so far developed independently and by that give rise to a completely new understanding of matrix scaling. It would also give a strong impulse for further developments in the field.
