  • Non-singular simplicial sets 
    Fjellbo, Rune Vegard S. (Doctoral thesis / Doktoravhandling, 2018)
    A simplicial set is said to be non-singular if its non-degenerate simplices are embedded. Let sSet denote the category of simplicial sets. We prove that the full subcategory nsSet whose objects are the non-singular simplicial ...
  • Normal oppdeling og produkt av endelige simplisielle mengder 
    Fjellbo, Rune Vegard S. (Master thesis / Masteroppgave, 2012)
    The canonical map from the Kan subdivision of a product of two finite simplicial sets to the product of the Kan subdivisions is a simple map, in the sense that its geometric realization has contractible point inverses.
