چکیده
We analyse with the algebraic, regularisation independent, cohomological B.R.S. methods, the renormalisability of torsionless N=2 supersymmetric non-linear σ models built on Kähler spaces. Surprisingly enough with respect to the common wisdom, we obtain an anomaly candidate, at least in the compact Ricci-flat case. In the compact homogeneous Kähler case, as expected, the anomaly candidate disappears.

Explicit solutions to the conifold equations with complex dimension n = 3, 4 in terms of complex coordinates (fields) are employed to construct the Ricci-flat Kähler metrics on these manifolds. The Kähler 2-forms are found to be closed. The complex realization of these conifold metrics are used in the construction of 2-dimensional non-linear sigma model with the conifolds as target spaces. The ...
متن کاملA C-estimate for the Parabolic Monge-ampère Equation on Complete Non-compact Kähler Manifolds
In this article we study the Kähler Ricci flow, the corresponding parabolic Monge Ampère equation and complete noncompact Kähler Ricci flat manifolds. In our main result Theorem 1 we prove that if (M, g) is sufficiently close to being Kähler Ricci flat in a suitable sense, then the Kähler-Ricci flow (1) has a long time smooth solution g(t) converging smoothly uniformly on compact sets to a comp...

متن کاملConstruction of Supersymmetric Nonlinear Sigma Models on Noncompact Calabi-Yau Manifolds with Isometry
We propose a class of N = 2 supersymmetric nonlinear sigma models on the noncompact Ricci-flat Kähler manifolds, interpreted as the complex line bundles over the hermitian symmetric spaces. Kähler potentials and Ricci-flat metrics for these manifolds with isometries are explicitly constructed by using the techniques of supersymmetric gauge theories. Each of the metrics contains a resolution par...
متن کاملLocal heterotic geometry in holomorphic coordinates
In the same spirit as done for N=2 and N=4 supersymmetric non-linear σ models in 2 space-time dimensions by Zumino and AlvarezGaumé and Freedman, we analyse the (2,0) and (4,0) heterotic geometry in holomorphic coordinates. We study the properties of the torsion tensor and give the conditions under which (2,0) geometry is conformally equivalent to a (2,2) one. Using additional isometries, we sh...
