2. Geometrical conditions.
3. Calculus methods.
II. Intersections.
1. Plane aplications. Intersection of convexe poligons. Intersection of segments. Intersection of half planes.
2. Aplications in space. Intersection of convex poligons. Intersection of half spaces.
III. Convex hulls.
1. Construction of convex hulls in plane.
2. Convex hulls in dimensions bigger than two.
3. Aplications in statistics.
IV. Problems of nearest points.
