Topology Tools Department of Mathematics, Faculty of Science, University of Benghazi, Libya Taha Guma el turki e-mail: taha1978_2002@yahoo.com The procedures in this application are related to point set topology , and they compute many new issues as the following :-1) Checking Normality ,all normal spaces over a given set and their number . 2) Minimal Basic open set , minimal basis. 3) Number of weakly-dimensional topologies . 4) Check if two topologies are homeomorphic or not . 5) Disconnected spaces and their number. 6) Disjoint proper open sets , disjoint proper closed sets , proper sets . 7) Neither open nor closed sets 8) The user can compute the special points in more flexible method than the method in[1]. Note:-For the following procedures the user have to enter ”n” the number of set points :- 1) All Extremal Topologies(n) ; # n the number of points. 2) Numberof Extremal Topologies(n); 3) AllNonTrivialMinimalTopologies(n); 4) NumberofNonTrivialMinimalTopologies(n); References:- [1] http://www.maplesoft.com/applications/view.aspx?SID=145571 [2] http://www.maplesoft.com/applications/view.aspx?SID=153617 [3] http://www.maplesoft.com/applications/view.aspx?SID=150631 [4] http://www.maplesoft.com/applications/view.aspx?SID=4122.
