Abstract: | Let S=cl(int S) be a subset of the plane, Q the set of points of local non-convexity of S, Qfinite, with p a point in (bdry S ker S) Q. If denotes the collection of allmaximal families of wedges of S having convex cover order m, m 1, then the members of are characterized in the following manner: For W
o a wedge of S, W
o is in if and only if for every w
o in W
o and every collection of points w
1, ...w
m in S, then w
i, wj] S for at least one pair i, j, 0 i<j m.AMS(MOS) Subject Classification 1970: Primary 52A10, 52A40. |
