Abstract
The results of A. Chiodo, Y. Ruan and M. Krawitz associate the mirror partner Calabi–Yau variety X to a Landau–Ginzburg orbifold if f is an invertible polynomial satisfying Calabi–Yau condition and the group G is a diagonal symmetry group of f. In this paper we investigate the Landau–Ginzburg orbifolds with a Klein quartic polynomial and G being all possible subgroups of , preserving the polynomial f and also the pairing in its Jacobian algebra. In particular, G is not necessarily abelian or diagonal. The zero–set of polynomial f, called Klein quartic, is a genus 3 smooth compact Riemann surface. We show that its mirror Landau–Ginzburg orbifold is with G being a –extension of a Klein four–group.
期刊介绍:
The Journal of Geometry and Physics is an International Journal in Mathematical Physics. The Journal stimulates the interaction between geometry and physics by publishing primary research, feature and review articles which are of common interest to practitioners in both fields.
The Journal of Geometry and Physics now also accepts Letters, allowing for rapid dissemination of outstanding results in the field of geometry and physics. Letters should not exceed a maximum of five printed journal pages (or contain a maximum of 5000 words) and should contain novel, cutting edge results that are of broad interest to the mathematical physics community. Only Letters which are expected to make a significant addition to the literature in the field will be considered.
The Journal covers the following areas of research:
Methods of:
• Algebraic and Differential Topology
• Algebraic Geometry
• Real and Complex Differential Geometry
• Riemannian Manifolds
• Symplectic Geometry
• Global Analysis, Analysis on Manifolds
• Geometric Theory of Differential Equations
