This poster discusses the discovery and use of previously unproved methods for solving counting problems using the fundamental ideas of the inclusion exclusion-principle and the Euler characteristic. While both methods use a weighted version of the Euler characteristic to determine the order of a union of finite sets, the first method can be used with contractible, planar graphs whereas the second method generalizes this idea to multi-dimensional complexes and their minimal complexes. These methods seem to be promising in their applications to subjects such as homology theory, Betti numbers, and abstract tubes.
