GST - Geometric spectral theory and applications

In this talk I consider the two parameter family of PDE ´s (generalized TFWequation):\[\Delta u + (\gamma u ^{– \phi) u=0,\]on $\mathbb{R}}3$, where\[\phi(x)= \frac{Z}{|x|}\int_{\mathbb{R}^{3} \frac{u}2(y)}{|x-y|} \, dy.\]Here, $Z>0$ is fixed and $\gamma \ge 0$, and $1

3}\|u\|_22 - Z$, for different values of $p$ and $\gamma$, where $u$ is thepositive solution of the generalized TFW equation. This is joint work withHeinz Siedentop (Ludwig Maximilians University).
