| Abstract: |
| In this paper we investigate the curvature integral inequalities. Using the properties of support functions of convex set and the outer parallel set in integral geometry, we give a simplified proof of the Gage-isoperimetric inequality and the entropy inequality for curvature. Finally, we obtain a new integral inequality for curvature. |
| Key words: curvature the Gage-isoperimetric inequality entropy inequality support function. |
