Maximal-area reduced bodies in the hyperbolic plane
Determine whether there exists, for a fixed minimal width (thickness) w, any reduced convex body in the hyperbolic plane H^2 whose area exceeds that of the quarter of a disk of radius w.
References
As a final remark, we note that the area of the quarter of the disk (which is also reduced) is greater than the area of the circle of the same thickness, and the author has no knowledge of any reduced body that has greater area in $H2$.
