According to the application to spatial topological relationship of point-set topology theory, we also develop point-set topology in temporal relationship field and form the definition and description of temporal relationship.

In the past, description on topological spatial relationship of GIS was based on basictheory of point set topology.

In terms of point set topology and combination topology, the formal definition of 3D spatial features are described as orientable n pseudomanifolds(0≤ n ≤3),and it can be represented by complexes which is th.

Study on CRM Model and Algorithm Based on Customer Cluster and Topological Theory;

Evaluation on the rationality of organization structure by means of topology;

Topology is more and more widely applied in the creative design of mechanism.

Using Liapunov-Schmidt method and topological degree theory,we proved some results for the(existence) of periodic solutions of nonlinear functional differential equations.

By using topological degree theory,the existence of solution to boundary-value problem of a class of fourth-order difference equations was discussed.

By applying the topological degree theory and some techniques of inequality,the uniqueness of the existence for the equilibrium point of the interval neural networks with mixed delays is worked out and the condition for global robust exponential stability is presented.
