### Statistical mechanics of Levin-Wen models, continued »

Corey Jones will describe the Levin-Wen model, constructing a local lattice Hamiltonian from a fusion category, and explain why we should study its statistical mechanical properties.

The Alexander polynomial is perhaps the knot invariant that has the greatest number of distinct definitions.

### Operator algebras ... in tensor categories? »

Corey will give an overview of why operator algebras are interesting, aimed at an algebraically-minded audience.

### Cyclic sieving »

Tony will intrroduce the idea of cyclic sieving, and then we'll all try to work out what connection there is, if any, to tensor categories.

### Categories enriched in braided tensor categories »

I'll recap last week (I know there will be several participants who missed it), perhaps sketch the classification theorem, or more likely talk about examples.

### Categories enriched in braided tensor categories »

There seems to be an interesting gap in the literature on enriched categories.

### Higher Frobenius-Schur indicators and eigenvalues of rotation in pivotal tensor categories, part 2 »

We'll discuss the notion of higher Frobenius-Schur indicators in pivotal fusion categories, why they're important, and how to compute them using only a small amount of data from the center of the category.

### Khovanov homotopy types »

Khovanov homology conventionally associates to a link a chain complex, whose homology is an invariant of the link.

### The Brauer-Picard groupoids of the ADE fusion categories »

Cain will talk about work in progress on understanding the Brauer-Picard groupoids of the ADE fusion categories.

### Functoriality for Khovanov homology »

Stephen will talk about work in progress on variants of Khovanov homology, which may afford an integral theory which is functorial in $S^3$.

### Free probability and skew symmetric functions »

### Modular tensor categories 2 »

We'll continuing discussing what modular tensor categories are and how they are related to other notions in category theory and condensed matter physics.
