This book offers an introduction to some combinatorial (also, set-theoretical) approaches and methods in geometry of the Euclidean space R m . The topics discussed in the manuscript are due to the field of combinatorial and convex geometry. The author’s primary intention is to discuss those themes of Euclidean geometry which might be of interest to a sufficiently wide audience of potential... Read more
