Maximilien Péroux (University of Pennsylvania) |

Coalgebras and comodules in stable homotopy theory. |

Homotopy Theory Seminar |

Time: 5pm |

In higher algebra, we study algebraic objects endowed with a multiplication that is associative only up to (coherent) homotopy, or commutative up to (coherent) homotopy. In this Brave new algebra, we ... More |

A model-independent construction of the Gray monoidal structure for (infinity,2)-categories |

Homotopy Theory Seminar |

Time: 6pm |

Location: Zoom |

In this talk I will describe joint work with Yuki Maehara in which we give a model-independent (i.e. a purely infinity-categorical) construction of the (non-symmetric) Gray monoidal structure on the i... More |

Martina Rovelli (University of Massachusetts Amherst) |

n-complicial sets as a model for (infinity, n)-categories |

Homotopy Theory Seminar |

Time: 5 pm |

Location: Zoom |

With the rising significance of (infinity, n)-categories, it is important to have easy-to-handle models for those and understand them as much as possible. In this introductory talk we will discuss how... More |

Central limit theorems for Sato-Tate sequences |

Algebra and Its Applications |

Adriana Salerno (Bates College) |

Hasse-Witt matrices and mirror toric pencils |

Algebra and Its Applications |

Time: 3:05 |

Rhiannon Griffiths (Case Western Reserve University) |

Enriched Model Categories for Functor Calculus |

Homotopy Theory Seminar |

Time: 5 pm |

Location: Zoom |

We present results necessary for developing model categories of enriched functors suitable for doing functor calculus. As a first example, we show how the discrete functor calculus of Bauer, Johnson a... More |

Decomposing the classifying diagram in terms of classifying spaces of groups |

Homotopy Theory Seminar |

Time: 5 pm |

Location: Zoom |

The classifying diagram was defined by Rezk and is a generalization of the nerve of a category; in contrast to the nerve, the classifying diagram of two categories is equivalent if and only if the cat... More |
