In this thesis, fundamental concepts of complex oriented matroids (phirotopes) are presented. The existing theory of duality, chirotopality and realisability is generalised to non-uniform phirotopes of arbitrary rank.
Furthermore, the relationship of phirotopes and Euclidean geometry is examined and Euclidean theorems are proven with the help of phirotopes.
Finally, it is proven that certain incidence theorems always hold true for non-chirotopal phirotopes, regardless of the realisability of the phirotopes.
