|$S_3$-covers of Schemes|
We analyze flat $S_3$-covers of schemes, attempting to create structures parallel to those found in the abelian and triple cover theories. We use an initial local analysis as a guide in finding a global description.
Keywords:nonabelian groups, permutation group, group covers, schemes

|Structure Theory of Totally Disconnected Locally Compact Groups via Graphs and Permutations |
Willis's structure theory of totally disconnected locally compact groups is investigated in the context of permutation actions. This leads to new interpretations of the basic concepts in the theory and also to new proofs of the fundamental theorems and to several new results. The treatment of Willis's theory is self-contained and full proofs are given of all the fundamental results.
Keywords:totally disconnected locally compact groups, scale function, permutation groups, groups acting on graphs
