Title: | String theory on elliptic curves: topology, algebraic geometry, and physics |

Seminar: | Department of Mathematics Colloquium |

Speaker: | Jonathan Rosenberg, University of Maryland |

Abstract: |

Supersymmetric string theory in 10 dimensions is the leading candidate for a unified theory of all the fundamental forces of nature. For maximal supersymmetry, it is usually assumed that space-time is the product of flat Minkowski spacetime with a compact Calabi-Yau manifold (a complex manifold with trivial canonical bundle). The simplest Calabi-Yau manifold is an elliptic curve, and in joint work with Chuck Doran and Stefan Mendez-Diez of the University of Alberta, we have recently made a thorough study of all "orientifold" string theories on elliptic curves (crossed with flat spacetime). I will explain how our findings illustrate deep connections between algebraic topology, algebraic geometry, and physics. |
