L2 -characteristic classes of Maslov–Trofimov of hamiltonian systems on the Lie algebra of the upper-triangular matrices
Jerzy Nowak (1998)
Fundamenta Mathematicae
Similarity:
We generalize the construction of Maslov-Trofimov characteristic classes to the case of some G-manifolds and use it to study certain hamiltonian systems.
Lefschetz coincidence formula on non-orientable manifolds
Daciberg Gonçalves, Jerzy Jezierski (1997)
Fundamenta Mathematicae
Similarity:
We generalize the Lefschetz coincidence theorem to non-oriented manifolds. We use (co-) homology groups with local coefficients. This generalization requires the assumption that one of the considered maps is orientation true.
Stratifications of teardrops
Bruce Hughes (1999)
Fundamenta Mathematicae
Similarity:
Teardrops are generalizations of open mapping cylinders. We prove that the teardrop of a stratified approximate fibration X → Y × ℝ with X and Y homotopically stratified spaces is itself a homotopically stratified space (under mild hypothesis). This is applied to manifold stratified approximate fibrations between manifold stratified spaces in order to establish the realization part of a previously announced tubular neighborhood theory.
