Hm, zuerst war ich misstrauisch, aber wenn die Mail direkt aus dem J. Edgar Hoover building kommt, dann MUSS die ja echt sein.

Mein Gott, mein Gott, warum hast du mich verlassen?

Moin,

man zeige:

Satz: Sei M eine riemannsche Mannigfaltigkeit. Zu jeder Karte
\varphi: U \to V
sei ein System differenzierbarer Funktionen
\Gamma_{\varphi,ij}^k: V \to \mathbb{R}
zugeordnet.

Diese definieren genau dann einen (eindeutig bestimmten) Zusammenhang, wenn sie beim Übergang zu einer anderen Karte \tilde\varphi:\tilde U \to \tilde V
der Umsetzungsformel
\begin{array}{lll}\sum_{j=1}^n \frac{\partial \gamma_k}{\partial x_j}(x) \Gamma_{\varphi,\mu\nu}^j(x) &=& \frac{\partial^2 \gamma_k}{\partial x_\mu \partial x\nu}(x) \\ &+& \sum_{1 \leq i,j \leq n} \frac{\partial \gamma_i}{\partial x_\mu}(x) \frac{\partial \gamma_j}{\partial x_\nu}(x) \Gamma_{\tilde\varphi,ij}^k(\gamma(x))\end{array}
mit \gamma = \tilde\varphi\varphi^{-1} genügen.

Achja, und als kleine Hilfe: Die \Gamma_{\varphi,ij}^k definieren genau dann einen eindeutigen Zusammenhang, wenn sich

Z_k(x) := \sum_{i,j} X_i(x)Y_i(x)\Gamma_{\varphi,ij}^k(x) + \sum_i X_i(x)\frac{\partial Y_k}{\partial x_i}

mit X_i,Y_i Vektorfelder selbst wie ein Vektorfeld transformiert, d.h. unter Ausnutzung von

 \tilde X_i(\gamma(x)) := \sum_{j=1}^n \frac{\partial \gamma_i}{\partial x_j}(x) X_j(x)
 \tilde Y_i(\gamma(x)) := \sum_{j=1}^n \frac{\partial \gamma_i}{\partial x_j}(x) Y_j(x)

muss wiederum mit

\tilde Z_k(x) := \sum_{i,j} \tilde X_i(x)\tilde Y_i(x)\Gamma_{\tilde\varphi,ij}^k(x) + \sum_i \tilde X_i(x)\frac{\partial \tilde Y_k}{\partial x_i}

gelten, dass

\tilde Z_i(\gamma(x)) := \sum_{j=1}^n \frac{\partial \gamma_i}{\partial x_j}(x) Z_j(x)

Zumindest, wenn ich das alles richtig verstanden hab.
Was mich zu meinem ursprünglichen Punkt zurückbringt: Mein Gott, mein Gott, warum hast du mich verlassen?

Gruß,

ich
