A reverse isoperimetric inequality for planar ($α$, $β$)--convex bodies

In this paper, we study a reverse isoperimetric inequality for planar convex bodies whose radius of curvature is between two positive numbers 0 < $α$ < $β$, called ($α$, $β$)--convex bodies. We show that among planar ($α$, $β$)--convex bodies of fixed perimeter, the extremal shape is a domain whose boundary is composed by two arcs of circles of radius $α$ joined by two arcs of circles of radius $β$.
