We prove three facts about intrinsic geometry of surfaces in a normed Minkowski space. When put together, these facts demonstrate a rather intriguing picture. We show that 1 geodesics on saddle surfaces in a space of any dimension behave as they are expected to: they have no conjugate points and thus minimize length in their homotopy class; 2 in contrast, every two-dimensional Finsler manifold can be locally embedded as a saddle surface in a 4 —dimensional space; and 3 geodesics on convex surfaces in a 3 —dimensional space also behave as they are expected to: on a complete strictly convex surface, no complete geodesic minimizes the length globally.

This approach experienced a very fast development in the last few decades and penetrated into many other mathematical disciplines, such as group theory, dynamical systems, and partial differential equations. The authors set a challenging goal of making the core parts of the book accessible to first-year graduate students. Most new concepts and methods are introduced and illustrated using simplest cases and avoiding technicalities. The book contains many exercises, which form a vital part of the exposition.
