2011-03-29 (15.00) : A chain property for cube-scalar matrices of order 3
At Euler building
Organized by Mathematical Engineering
Speaker :
Jean-Pierre TIGNOL (UCL)
Abstract :
Matrices a of order 3 such that a3 is a scalar matrix are the vertices of a directed graph in which an edge goes from a to b
when aba^{-1}b^{-1}= e^{2i\pi/3}. This talk will present a proof that any two cube-scalar matrices can be connected by a path of length at
most 4, using some exceptional algebraic structures.
