Metrics with Prescribed Horizontal Bundle on Spaces of Curves

چکیده
We study metrics on the shape space of curves that induce a prescribed splitting of the tangent bundle. More specifically, we consider reparametrization invariant metrics G on the space Imm(S,R) of parametrized regular curves. For many metrics the tangent space TcImm(S ,R) at each curve c splits into vertical and horizontal components (with respect to the projection onto the shape space Bi(S ,R) = Imm(S,R)/Diff(S) of unparametrized curves and with respect to the metric G). In a previous article we characterized all metrics G such that the induced splitting coincides with the natural splitting into normal and tangential parts. In these notes we extend this analysis to characterize all metrics that induce any prescribed splitting of the tangent bundle.

Tautological Ring of Strata of Differentials
Strata of k-differentials on smooth curves parameterize sections of the k-th power of the canonical bundle with prescribed orders of zeros and poles. Define the tautological ring of the projectivized strata using the κ and ψ classes of moduli spaces of pointed smooth curves along with the class η = O(−1) of the Hodge bundle. We show that if there is no pole of order k, then the tautological rin...
متن کاملAffine Geometry of Strata of Differentials
Affine varieties among all algebraic varieties have simple structures. For example, an affine variety does not contain any complete algebraic curve. In this paper we study affine related properties of strata of k-differentials on smooth curves which parameterize sections of the k-th power of the canonical line bundle with prescribed orders of zeros and poles. We show that if there is a prescrib...
متن کاملFixed point of generalized contractive maps on S^{JS}- metric spaces with two metrics
In this paper we prove existence of fixed point theorems for Z-contractive map, Geraghty type contractive map and interpolative Hardy-Rogers type contractive mapping in the setting of SJS- metric spaces with two metrics. Examples are constructed to high light the significance of newly obtained results.
متن کاملON THE LIFTS OF SEMI-RIEMANNIAN METRICS
In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a semi-Riemannian vector bundle over a semi-Riemannian manifold M, then by using an arbitrary (linear) connection on E, we can make E, as a...
متن کاملAn Overview of the Riemannian Metrics on Spaces of Curves Using the Hamiltonian Approach
Here shape space is either the manifold of simple closed smooth unparameterized curves in R or is the orbifold of immersions from S to R modulo the group of diffeomorphisms of S. We investige several Riemannian metrics on shape space: L-metrics weighted by expressions in length and curvature. These include a scale invariant metric and a Wasserstein type metric which is sandwiched between two le...
