Our research:
The following joint research with
Professor Dan Dugger was undertaken while I was a postdoc at the
University of Oregon (2007-2010).
Rigidification of
quasi-categories. Here we prove that the mapping space between two objects in the rigidification of a
quasi-category
is isomorphic to the nerve of the category of necklaces connecting those
two objects. On the arXiv.
Mapping spaces in
quasi-categories. Here we prove that the mapping spaces in a quasi-category are as one who is familiar
with the homotopy mapping complexes of Dwyer-Kan might expect. We prove that various formulations of these
mapping spaces found in Lurie's book
HTT can all be obtained in this way. Finally we give a self-contained proof of Lurie's result that the
Joyal model structure on simplicial sets is Quillen equivalent to
Bergner's model structure on simplicial categories. On the arXiv.
