Jens Iseler,Andreas Lesser,Reinhard NiehuisA bundle in?topology is a union of fibers parametrized by its base space and glued together by the topology of the total space. On the other hand, a . is a bundle with an additional structure derived from the action of a topological group on the fibers. A fiber bundle is a locally trivial fibration having covering homotopy property.

LASH

Gerald Schubert,Georg Hager,Holger Fehskeles and vector bundles was born through the distribution of signs of the derivatives of the plane curves at every point. . the recognition of the theory of fiber bundles as a discipline of mathematics came through the work of H. Whitney (1907–1989), H. Hopf (1894–1971), E. Stiefel (1909–1978), J. Feldbau (1914–1945) and some others.

This book will promote the scope, power and active learning of the subject, all the while covering a wide range of theory and applications in a balanced unified way.

Finally, this chapter presents some interesting applications of homotopy, fundamental and higher homotopy groups in analysis, geometry, algebra, matrix theory, atmospheric science, vector field and extension problems and some others.
