Charles Ehresmann's concepts in differential geometry
We outline some of the tools C. Ehresmann introduced in Differential Geometry (fiber bundles, connections, jets, groupoids, pseudogroups). We emphasize two aspects of C. Ehresmann's works: use of Cartan notations for the theory of connections and semi-holonomic jets.
Cheeger inequalities for unbounded graph Laplacians
We use the concept of intrinsic metrics to give a new definition for an isoperimetric constant of a graph. We use this novel isoperimetric constant to prove a Cheeger-type estimate for the bottom of the spectrum which is nontrivial even if the vertex degrees are unbounded.
Cheeger's inequality with a boundary term.
Chern numbers for singular varieties and elliptic homology.
Chern-Simons terms as an example of the relations between mathematics and physics
Christoffer Symbols and Connection Forms on Infinite-Dimensional Fibre Bundles
Circle bundles, adiabatic limits of -invariants and Rokhlin congruences
We present a direct analytic treatment of the Rokhlin congruence formula R2 by calculating the adiabatic limit of -invariants of Dirac operators on circle bundles. Extensions to higher dimensions are obtained.

Circle-valued Morse theory and Reidemeister torsion.
