Section extension from hyperbolic geometry of punctured disk and holomorphic family of flat bundles
《Science China Mathematics》2011年第8期1767-1802,共36页SIU Yum-Tong 
supported by Grant 1001416 of the National Science Foundation
The construction of sections of bundles with prescribed jet values plays a fundamental role in problems of algebraic and complex geometry.When the jet values are prescribed on a positive dimensional subvariety,it is h...

Twisted analytic torsion被引量:1
《Science China Mathematics》2010年第3期555-563,共9页MATHAI Varghese 
We review the Reidemeister, Ray-Singer’s analytic torsion and the Cheeger-Mller theorem. We describe the analytic torsion of the de Rham complex twisted by a flux form introduced by the current authors and recall its...

Cohomology of bundles on homological Hopf manifolds
《Science China Mathematics》2009年第12期2688-2698,共11页LIBGOBER Anatoly 
supported by National Science Foundation
We discuss the properties of complex manifolds having rational homology of S 1 × S 2n?1 including those constructed by Hopf, Kodaira and Brieskorn-van de Ven. We extend certain previously known properties of cohomolo...

Harmonic maps into loop spaces eliminate of compact Lie groups
《Science China Mathematics》2008年第4期695-706,共12页Armen Glebovich SERGEEV 
This work was partly supported by the RFBR(Grant Nos.04-01-00236,06-02-04012);by the program of Support of Scientific Schools(Grant No.1542.2003.1);by the Scientific Program of RAS"Nonlinear Dynamics"
We study harmonic maps from Riemann surfaces M to the loop spacesΩG of compact Lie groups G,using the twistor approach.We conjecture that harmonic maps of the Riemann sphere CP^1 intoΩG are related to Yang-Mills G-f...

Project supported by TWAS GR no. 86-30.
The lifting of diffusion processes and differential operators on a Riemannian base spaceM to diffusion processes on a principal bundle P and differential operators on the associatedbundle are studied. It has been prov...
