  Differential geometry and topology - Wikipedia, the free encyclopedia
Differential geometry is the study of geometry using calculus.
Initially and up to the middle of the nineteenth century, differential geometry was studied from the extrinsic point of view: curves, surfaces were considered as lying in a Euclidean space of higher dimension (for example a surface in an ambient space of three dimensions).
Finsler geometry has the Finsler manifold as the main object of study — this is a differential manifold with a Finsler metric, i.e.

The apparatus of differential geometry is that of calculus on manifolds: this includes the study of manifolds, tangent bundles, cotangent bundles, differential forms, exterior derivatives, integrals of p-forms over p-dimensional submanifolds and Stokes' theorem, wedgeproducts, and Lie derivatives.

 Finsler Geometry Is Just Riemannian Geometry without the Quadratic Restriction   (Site not responding. Last check: 2007-10-20)
The key idea in Finsler geometry is to consider the projectivized tangent bundle PTM (i.e., the bundle of line elements) of the manifold M. The main reason is that all geometric quantities constructed from F are homogeneous of degree zero in y and thus naturally live on PTM, even though F itself does not.
The extension of the Gauss-Bonnet formula to Finsler geometry has been considered in [7], in which the relevant curvature forms were introduced and studied.
As is well known, Riemannian geometry can be handled, elegantly and efficiently, by tensor analysis on M. Its handicap with Finsler geometry arises from the fact that the latter needs more than one space, for instance PTM in addition to M, on which tensor analysis does not fit well.

Finsler geometry has broader applications in many areas of science and will continue to develop through the efforts of many geometers around the world.
Viewing Finsler spaces as regular metric spaces, the author discusses the problems from the modern metric geometry point of view.
The book begins with the basics on Finsler spaces, including the notions of geodesics and curvatures, then deals with basic comparison theorems on metrics and measures and their applications to the Levy concentration theory of regular metric measure spaces and Gromov's Hausdorff convergence theory.

Finsler geometry has Finsler manifold as the main object of study, it is a differential manifold with Finsler metric, i.e.
Riemannian geometry has Riemannian manifold as the main object of study, its smooth manifolds with an additional structure which makes them look infinitesimally like Euclidean space and therefore allow to generalise the notion from Euclidean geometry such as gradient of a function, divergence, length of curves and so on.

 Finsler geometry in classical mechanics and in Bianchi cosmological models   (Site not responding. Last check: 2007-10-20)
The second example is particularly enlightening as the introduction of Finsler geometry overcomes the critical problems which cause the Jacobi (Riemannian) metric to fail.
The Finsler geometrodynamical approach is particularly useful also because it gives a gauge-invariant characterization of chaos, which is always important, but becomes essential for General Relativistic dynamical systems.
Finsler's geometry was developed by Berwald (1926), Eisenhart (1927), Knebelman (1929), Cartan (1934) and Rund (1959) [17].

 Finsler Geometry? Who ordered that?   (Site not responding. Last check: 2007-10-20)
Here I have some remarks on Finsler geometry: It is considered to be a generalization of Riemnannian geometry, on tangent bundles, with anisotropies of metric (depending on direction), which is more sophisticated and with less experimental evidence for such extensions.
The conclusion is that we can not avoid Finsler geometry even in the usual (Einstein) gravity if the generic off-diagonal metrics and nonholonomic frames are considered.
The main problem is that the bulk of monographs on Finsler geometry were written to emphasize more general constructions than the the Riemannian ones, just on tangent bundles.

It is known that the flag curvature of any projective Finsler metric is a scalar function of tangent vectors (the flag curvature must be a constant if it is Riemannian).
In this paper, we discuss the classification problem on projective Finsler metrics of constant flag curvature.

The differential geometry of a regular Lagrangian is more involved than that of classical kinetic energy and consequently is far from being Riemannian.
Nevertheless, such geometries are playing an increasingly important role in a wide variety of problems in fields ranging from relativistic optics to ecology.
