Covers the maximal and prime ideals of the incidence algebra, derivations and isomorphisms, radicals and additional ring-theoretic properties. This book presents combinatorial discussions that include a study of the Mobius function, reduced incidence subalgebras, and the coalgebra approach to incidence algebras.
