Mark van Hoeij (FSU) |

The Complexity of Computing all Subfields of an Algebraic Number Field |

Algebra and Its Applications |

Time: 3:35 PM |

Location: LOV 104 |

For a finite separable field extension K/k, all subfields can be obtained by intersecting so-called principal subfields of K/k. The talk will present a way to quickly compute these intersections. If t... More |

John Bergschneider (FSU) |

Finite 2-Stratifold Groups |

Topology and Geometry Seminar |

Time: 3:35p |

Location: 201 |

2-Stratifolds are a generalization of closed surfaces in that they contain simple closed curves where several sheets meet. Currently, there is no general classification of these spaces or their funda... More |

Alex Reznikov (FSU) |

A sum-product estimate in finite fields, and applications |

Analysis & PDE |

Time: 2:30 |

Location: LOV 106 |

We will start reading the paper by Bourgain, Katz and Tao on the so-called "sum-product" estimates. |

Paolo Aluffi (FSU) |

Newton-Okounkov bodies and Segre classes. |

Algebra and Its Applications |

Time: 3:35 PM |

Location: LOV 104 |

We will present a new approach to the computation of the Segre class of a subscheme of projective space, based on the construction of a suitable Newton-Okounkov body. The result may be viewed as a co... More |
