Fixed points on Klein bottle fiber bundles over the circle
D. L. Gonçalves, D. Penteado, J. P. Vieira (2009)
Fundamenta Mathematicae
Similarity:
The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S¹ for spaces which are fiber bundles over S¹ and the fiber is the Klein bottle K. We classify all such maps which can be deformed fiberwise to a fixed point free map. The similar problem for torus fiber bundles over S¹ has been solved recently.
On Weil Bundles of the First Order

Similarity:
The descriptions of Weil bundles, lifts of functions and vector fields are given. Actions of the automorphisms group of the Whitney sum of algebras of dual numbers on a Weil bundle of the first order are defined.

Maximality of dual coactions on sectional C*-algebras of Fell bundles and applications
Alcides Buss, Siegfried Echterhoff (2015)
Studia Mathematica
Similarity:
We give a simple proof of the maximality of dual coactions on full cross-sectional C*-algebras of Fell bundles over locally compact groups. This result was only known for discrete groups or for saturated (separable) Fell bundles over locally compact groups. Our proof, which is derived as an application of the theory of universal generalised fixed-point algebras for weakly proper actions, is different from these previously known cases and works for general Fell bundles over locally compact...
On oriented vector bundles over CW-complexes of dimension 6 and 7
Martin Čadek, Jiří Vanžura (1992)
Commentationes Mathematicae Universitatis Carolinae
Similarity:
Necessary and sufficient conditions for the existence of -dimensional oriented vector bundles () over CW-complexes of dimension with prescribed Stiefel-Whitney classes , and Pontrjagin class are found. As a consequence some results on the span of 6 and 7-dimensional oriented vector bundles are given in terms of characteristic classes.
