Quantitative Néron theory for torsion bundles
Let R be a discrete valuation ring with algebraically closed residue field, and consider a smooth curve CK over the field of fractions K. For any positive integer r prime to the residual characteristic, we consider the finite K-group scheme PicCK [r] of r-torsion line bundles on CK . We determine when there exists a finite R-group scheme, which is a model of PicCK [r] over R; in other words, we...
متن کاملComplex Valued Analytic Torsion for Flat Bundles and for Holomorphic Bundles with (1,1) Connections
The work of Ray and Singer which introduced analytic torsion, a kind of determinant of the Laplacian operator in topological and holomorphic settings, is naturally generalized in both settings. The couplings are extended in a direct way in the topological setting to general flat bundles and in the holomorphic setting to bundles with (1,1) connections, which using the Newlander-Nirenberg Theorem...
متن کاملAxioms for Higher Torsion Invariants of Smooth Bundles
We explain the relationship between various characteristic classes for smooth manifold bundles known as “higher torsion” classes. We isolate two fundamental properties that these cohomology classes may or may not have: additivity and transfer. We show that higher Franz-Reidemeister torsion and higher Miller-Morita-Mumford classes satisfy these axioms. Conversely, any characteristic class of smo...
متن کاملGauge Theory for Fiber Bundles
Gauge theory usually investigates the space of principal connections on a principal fiber bundle (P, p, M, G) and its orbit space under the action of the gauge group (called the moduli space), which is the group of all principal bundle automorphisms of P which cover the identity on the base space M. It is the arena for the Yang-Mills-Higgs equations which allows (with structure group U (1) × SU...
متن کاملK-Theory Torsion
The Chern isomorphism determines the free part of the K-groups from ordinary cohomology. Thus to really understand the implications of K-theory for physics one must look at manifolds with K-torsion. Unfortunately there are not many explicit examples, and usually for very symmetric spaces. Cartesian products of RPn are examples where the order of the torsion part differs between K-theory and ord...
