For a convex body $K$ in $\mathbb{R}^n$, we introduce and study the extremal general affine surface areas, defined by \[ {\rm IS}_{\varphi}(K):=\sup_{K^\prime\subset K}{\rm as}_{\varphi}(K),\quad os}_{\psi}(K):=\inf_{K^\prime\supset as}_{\psi}(K) \] where ${\rm as}_{\varphi}(K)$ as}_{\psi}(K)$ are $L_\varphi$ $L_\psi$ area of $K$, respectively. We prove that there exist bodies achieve supremum ...

We study Blaschke-Santal\'o diagrams associated to the torsional rigidity and first eigenvalue of Laplacian with Dirichlet boundary conditions. work under convexity volume constraints, in both strong (volume exactly one) weak at most form. discuss some topological (closedness, simply connectedness) geometric (shape boundaries, slopes near point corresponding ball) properties these diagrams, als...
