Title: Make Lattices Colourful
Abstract:
It is neither possible to decide on the basis of the subgroup lattice of a group \(G\), whether \(G\) is abelian nor to detect the normal subgroups of \(G\). This disadvantage can be compensated by colouring the lattice according to the fusion induced by conjugation in \(G\). In this talk we will discuss more benefits of this notion.
