DESCRIPTION:Over the last decade or so\, there have been many
proposed definitions of (∞\, 1)-categories\, but t
here have also been just as many results showing t
hat these definitions give rise to the same homoto
py theory\,\nand in particular\, the same homotopy
category. However\, there is also a slightly fine
r invariant\, a 2-category first constructed by Jo
yal and more recently studied by Riehl and Verity\
, which captures more of the formal category theor
y that one can do with (∞\, 1)-categories. In this
talk\, I will recall the construction of this 2-c
ategory and explain the sense in which it is theor
y-independent.
