This leads to the investigation of the corresponding heat equation which is the parabolic initial value problem \begin{eqnarray*} \frac{\partial u^{i}}{\partial t}-\frac{\partial ^{2}u^{i}}{\partial x^{2}} &=&\Gamma _{hk}^{i}\left( u,\frac{\partial u}{\partial x}\right) \frac{% \partial u^{h}}{\partial x}\frac{\partial u^{k}}{\partial x}\mbox{ in }% M\times \lbrack 0,T), \\ u\left( x,0\right) &=&f\left( x\right) ;\ i=1,...,n. \end{eqnarray*}% The existence of a global in time solution $u\left( x,t\right)$ and its subsequent convergence to a closed geodesic $u_{\infty} \colon M\rightarrow N$ as $t\rightarrow \infty$, are dealt with. Appropriate concepts arising from the Finslerian nature of the problem are introduced. [ Fulltext-pdf  (146  KB)] for subscribers only.
