We introduce for convex domains of constant width a measure of asymmetry and show that the most symmetric domains are circular discs and the most asymmetric domains are Reuleaux triangles.

In this paper,the kinematic measure for a rectangle in convex domain is studied.

In this paper ,by using the methods of kinematic measure on convex domain,we discuss the distribution of the points of intersection of the convex domain and rectangle lattice,and get a conclusion of its distribution.

Whitley,and obtain the sharp results about distortiontheorems for the holomorphic mappings between convex domains in the Banach spaces.
