Meromorphic Differentials with Twisted Coefficients on Compact Riemann Surfaces
This note is to concern a generalization to the case of twisted coefficients of the classical theory of Abelian differentials on a compact Riemann surface. We apply the Dirichlet’s principle to a modified energy functional to show the existence of differentials with twisted coefficients of the second and third kinds under a suitable assumption on residues. 1 Main results and discussion Let X be...
متن کاملQuadratic Differentials and Foliations
This paper concerns the interplay between the complex structure of a Riemann surface and the essentially Euclidean geometry induced by a quadratic differential. One aspect of this geometry is the " trajectory structure" of a quadratic differential which has long played a central role in Teichmfiller theory starting with Teichmiiller's proof of the existence and uniqueness of extremal maps. Ahlf...
متن کاملEfficient half-quadratic regularization with granularity control
In the last decade, several authors have proposed edge preserving regularization (EPR) methods for solving ill posed problems in early vision. These techniques are based on potentials derived from robust M–Estimators. They are capable of detecting outliers in the data, finding the significant borders in noisy images and performing edge–preserving restorations. These methods, however, have some ...
متن کاملHalf-quadratic transportation problems
We present a primal–dual memory efficient algorithm for solving a relaxed version of the general transportation problem. Our approach approximates the original cost function with a differentiable one that is solved as a sequence of weighted quadratic transportation problems. The new formulation allows us to solve differentiable, non– convex transportation problems.
متن کاملMeromorphic Almost Rigid Geometric Structures
We study the local Killing Lie algebra of meromorphic almost rigid geometric structures on complex manifolds. This leads to classification results for compact complex manifolds bearing holomorphic rigid geometric structures.
