2-dimensional TFTs via modular $\infty$ -operads

Jan Steinebrunner

This lecture series is based on joint work in progress with Shaul Barkan, as well as work in progress of the author. The five sections of these notes correspond to the five lecture…

Envelopes for Algebraic Patterns

Shaul Barkan, Rune Haugseng, Jan Steinebrunner

We generalize Lurie's construction of the symmetric monoidal envelope of an $\infty$ -operad to the setting of algebraic patterns. This envelope becomes fully faithful when sliced o…

The space of traces in symmetric monoidal infinity categories

Jan Steinebrunner

We define a tracelike transformation to be a natural family of conjugation invariant maps $T_{x, C} : h o m_{C} (x, x) \to h o m_{C} (1, 1)$ for all dualisable objects $x$ in any symmetric monoi…
