(English Abstract)
For n points pi on the m-dimensional plane R^m and a fixed range r, consider a set Ti containing points the distances from pi of which are less than or equal to r. In case m=1, Ti is an interval on a line, it is a circle on a plane when m=2. For the vertices corresponding to the sets Ti, there is an edge between the vertices if the two sets intersect. Then this graph is called an intersection graph G. For m=1, G is called a proper interval graph and for m=2, it is called an unit disk graph. In this paper, we are concerned in the intersection graph G(r) when r changes. In particular, we consider the problem to find the minimum r such that G(r) is connected. For this problem, we propose an O(n) algorithm for the proper interval graph and an O(n^2logn) algorithm for the unit disk graph. For the dynamic enviroment in which the points on line are added or deleted, we give an O(logn) algorithm for the problem.
