The -floating area, curvature entropy, and isoperimetric inequalities on the sphere
Florian Besau, Elisabeth M. Werner
We explore analogs of classical centro-affine invariant isoperimetric inequalities, such as the Blaschke--Santaló inequality and the -affine isoperimetric inequalities, for co…

Floating bodies and duality in spaces of constant curvature
Florian Besau, Elisabeth M. Werner
We investigate a natural analog to Lutwak's -affine surface area in -dimensional spherical, hyperbolic and de Sitter space. In particular, we show that these curvature measur…
