In geometry, a hyperplane is a subspace whose dimension is one less than that of its ambient space. If a space is 3dimensional then its hyperplanes are the 2dimensional planes, while if the space is 2dimensional, its hyperplanes are the 1dimensional lines. The handbook contains survey chapters in classical and new studies in geometric algorithms.
A nite hyperplane arrangement a is a nite set of a ne hyperplanes in some vector space v. In geometry and combinatorics, an arrangement of hyperplanes is an arrangement of a finite set a of hyperplanes in a linear, affine, or projective space s. We will not consider in nite hyperplane arrangements or arrangements of general subspaces or other objects though they have many interesting properties, so we will simply use the term arrangement for a nite hyperplane arrangement. The present book is devoted to several selected topics in the emerging theory of pattern recognition on oriented matroids.
