Groups and Combinatorics Seminar
Bojan Kuzma (University of Primorska, Slovenia)
will speak on
Graphs and general preservers of zero products
at 1pm on Tuesday 27th of November in MLR2
Abstract: We survey some results in preserver problems where graphs were used as the main tool. In particular, the classification of maps which preserve Jordan orthogonality (AB+BA=0) reduces to the fact that a certain graph is a core and has chromatic number 4. We also give a classification of certain matrices (rank-ones, semisimple, non-derogatory) in terms of a commuting graph.
All welcome.
