In this paper, the authors study the existence of nontrivial solutions for the Hamiltonian systems z(t) = J△↓H(t, z(t)) with Lagrangian boundary conditions, where ^H(t,z)=1/2(^B(t)z, z) + ^H(t, z),^B...

The authors establish a Cheeger-Müller type theorem for the complex valued analytic torsion introduced by Burghelea and Hailer for fiat vector bundles carrying nondegenerate symmetric bilinear forms. As a consequence...
