Two Bonnesen-style inequalities are obtained for the relative in-radius of one convex body with respect to another in n-dimensional space. Both reduce to the known planar inequality; one sharpens the relative isoperi-metric inequality, the other states that a quadratic polynomial is negative at the inradius.

Bonnesen style inequalities and isoperimetric deficit upper limit 71 a domain in space Rn, the convex hull does not always increase the volume and at the same time decrease the surface area. Therefore the convexity of domain is fundamental for isoperimetric problem in space Rn.

Let Γ be an oval curve in the Euclidean plane R2 enclosing a domain D of area A. Let P be the length and the curvature of Γ, then is a Bonnesen-type inequality for the hyperbolic plane, derived in Section 3. The limiting case as κ → 0 in either of Theorems 2.1 and 3.3 yields the classical Bonnesen inequality (1), as described above. A brief and direct proof of (1) using kinematic arguments, also described in [San76], is presented at the close of Sep 24, 2008 Bonnesen-Style Isoperimetric Inequalities. by Robert Osserman.

[1] T. Bonnesen, "Ueber eine Verschärferung der isoperimetische Ungleichheit des Kreises in der Ebene und auf die First, note that we have exhibited nine inequalities of Bonnesen type: (1I)-(13), (16)-(18), and (21)-(23). The last three obviously have all three properties of a Bonnesen inequality, since the right-hand side can vanish only if R = p, in which case the curve must be a circle of radius R. Of the Bonnesen's inequality is an inequality relating the length, the area, the radius of the incircle and the radius of the circumcircle of a Jordan curve. It is a strengthening of the classical isoperimetric inequality. A Bonnesen-style inequality strengthens the isoperimetric inequality by im- plying that the isoperimetric deficit L - 4nA of a closed plane curve y is greater than some positive quantity E(y Reverse Bonnesen-style inequalities Theorem 3.1. The inequality is strict whenever t\in (0,\rho _ {m}) or t\in (\rho _ {M}, +\infty ). When t=\rho _ {m} or Proof.
