Simon A. Zebelo,Massimo E. Maffeiy construct from a given (regular, finite) CW-complex a second CW-complex that is homotopy equivalent to the first but has fewer cells. As the upshot of this chapter we then show that one can use this theory in order to construct minimal free resolutions (see also ). Discrete Morse theory has fou

https://doi.org/10.1007/978-94-017-6251-9Much of the algebraic combinatorics described in Chapter 1 was originally developed with topological applications in mind. We give a brief description of some of the main features of these applications.

In dimension 2, the Selberg arrangement of five lines is shown below. We shall use this arrangement to illustrate definitions and results in Section 1.11.
