Specialized Plan for the 2017/2018 Winter Semester
This semester we will focus on Goodwillie's functor calculus from an
\(\infty\)-categorical viewpoint. As source material we will consider the relevant sections from Lurie's Higher Algebra, as well as more classical sources. We will also consider some applications and examples from the theory.
Our plan will be very roughly guided by the plan of the AG given here.
The purpose of this seminar is to study the general theory of higher categories and its applications. Higher category theory, especially the theory of
\((\infty,n)\)-categories, provides a powerful language for handling the complexity of encoding relations, relations between relations, and "so on".
This language has been applied to questions in homotopy theory, derived algebra, derived algebraic geometry, topological field theory, and computer science. In addition to conceptualizing classical results by placing them in a more general context, they have proven essential for studying homotopy theories themselves.
The exact subject matter of the seminar will be determined by the participants and their interests. In particular, participants are encouraged to speak about related topics arising in recent research papers. We also encourage participants to give talks on various foundational topics including, but not limited to, models for
\((\infty,n)\)-categories, presentable \(\infty\)-categories, higher topoi, stable \(\infty\)-categories, (higher) operad theory, derived schemes, (derived) stacks, the cobordism hypothesis, bicategories, higher Picard and Brauer groups...and beyond!
