On the relative category in the brake orbits problem
In this paper %dedicated to the memory of Edward Fadell and Sufian Husseini
we show how the notion of the Lusternik-Schnirelmann relative category can be used
to study a multiplicity problem for brake orbits in a potential well
which is homeomorphic to the $N$-dimensional unit disk.
The estimate of the relative category of the set of chords with endpoints on the
$(N-1)$-unit sphere was shown to the third author by
Fadell and Husseini while he was visiting the University of Wisconsin at Madison.
期刊介绍:
Topological Methods in Nonlinear Analysis (TMNA) publishes research and survey papers on a wide range of nonlinear analysis, giving preference to those that employ topological methods. Papers in topology that are of interest in the treatment of nonlinear problems may also be included.
