The main thing happening in my end of the world is that it’s relocated from Europe back to North America. I’m taking up a teaching postdoc position in the Mathematics and Computer Science department at… 1,425 more words

#### TQFT - elementary examples and consequences

In TQFT Axioms – 1, I shared the axioms for a *topological quantum field theory* as detailed in Kock. Any functor meeting these axioms count. 1,004 more words

#### TQFT's in Vienna - Part 2

To continue from the previous post…

**Twisted Differential Cohomology**

Ulrich Bunke gave a talk introducing differential cohomology theories, and Thomas Nikolaus gave one about a twisted version of such theories (unfortunately, perhaps in the wrong order). 2,156 more words

#### TQFT's in Vienna - Part 1

So I spent a few weeks at the Erwin Schrodinger Institute in Vienna, doing a short residence as part of the program “Modern Trends in Topological Quantum Field Theory… 1,674 more words

#### A Slapdash Introduction to TQFTs from the Ground Up, Part III.

In parts I and II, I defined the notions of manifolds and cobordisms which make up some of the mathematical machinery for the general relativity side of topological quantum field theory. 321 more words

#### A Slapdash Introduction to TQFTs from the Ground Up, Part I.

Topological quantum field theory is an interest of mine which has grown in intensity over the last year. I have, however, made the unfortunate mistake of attempting to describe some of these concepts to family and friends with results ranging from eyes-glazed-over incomprehension to “That’s really cool but my brain hurts now.” As a result of this, I have decided to try to improve my exposition by way of writing a cursory introduction to the subject requiring little more than a familiarity with sets, functions, and vector spaces. 401 more words

#### Seminar on the Cobordism Hypothesis and (Infinity,n)-Categories

Well, it’s been a while, but it’s now a new semester here in Hamburg, and I wanted to go back and look at some of what we talked about in… 3,231 more words
