Tommaso Ruggeri,Masaru Sugiyamale for the indices of certain elliptic complexes. These results have implications for the volumes of fundamental domains of discrete subgroups, and in refining these implications we also develop a proportionality principle for equivariant characteristic classes.

Rational Lawmaking under Reviewng the last decade about the value of the square of the length of the mean curvature vector for isometric immersions. However this is clearly a special case of more general results concerning the square of the length of the tension field of maps (in general, not isometric) of riemannian manifolds.

cided to celebrate this event by preparing a jubilee volume of contributed articles in the two main fields of research marked by Lichnerowicz‘s work, namely differential geometry and mathematical physics. Limitations of space and time did not enable us to include papers from all Lichnerowicz‘s frien

Inductive Reasoning in Repeated Gamesrtinet’s methods [15], we prove the nullity of certain Pontjargin classes for totally regular systems (their successive derived systems are of constant rank). The same methods could be applied to the study of local equivalence of .-structures.
