On the Invariant Spectrum of S1−invariant Metrics on S
A theorem of J. Hersch (1970) states that for any smooth metric on S, with total area equal to 4π, the first nonzero eigenvalue of the Laplace operator acting on functions is less than or equal to 2 (this being the value for the standard round metric). For metrics invariant under the standard S-action on S, one can restrict the Laplace operator to the subspace of S-invariant functions and consi...
متن کاملCircle Bundles and the Kreck-Stolz Invariant
We present a direct analytic calculation of the s-invariant of KreckStolz for circle bundles, by evaluating the adiabatic limits of I invariants. We believe that this method should have wider applications.
متن کاملStable Approximations of Certain Vector Bundles
0 −−−−→ O s −−−−→ E0 s∗ −−−−→ I −−−−→ 0. As usual, s is the distinguished nonzero global section of E0. The determinant line bundle of E0 is trivial, while the second Chern class is equal to the integer k. If X is in particular an algebraic surface, and H a fixed ample line bundle, then we can talk about slope-stability with respect to H. The bundle E0 is only slopesemistable, of slope 0, but t...
متن کاملSmooth Compactifications of Certain Normic Bundles
For a finite cyclic Galois extension of fields K/k of degree n and a separable polynomial of degree dn or dn−1, we construct an explicit smooth compactification X → Pk of the affine normic bundle X0 given by NK/k(~z) = P (x) 6= 0, extending the map X0 → Ak, where (~z, x) 7→ x. The construction makes no assumption of the characteristic of k, making it a suitable departure point for studying the ...
متن کاملη-invariant and flat vector bundles II
We first apply the method and results in the previous paper to give a new proof of a result (hold in C/Z) of Gilkey on the variation of ηinvariants associated to non self-adjoint Dirac type operators. We then give an explicit local expression of certain η-invariant appearing in recent papers of Braverman-Kappeler on what they call refined analytic torsion, and propose an alternate formulation o...
