Riemannian Geometry

The study of Manifolds having a complete Riemannian Metric. Riemannian geometry is a general space based on the Line Element

\begin{displaymath}
ds=F(x^1, \ldots, x^n; dx^1, \ldots, dx^n),
\end{displaymath}

with $F(x,y)>0$ for $y\not=0$ a function on the Tangent Bundle $TM$. In addition, $F$ is homogeneous of degree 1 in $y$ and of the form

\begin{displaymath}
F^2=g_{ij}(x)\,dx^i\,dx^j
\end{displaymath}

(Chern 1996). If this restriction is dropped, the resulting geometry is called Finsler Geometry.
