There is a somewhat mysterious relationship between the trefoil knot and the 3-dimensional associahedron that was observed by Loday. Basically, there is a natural way of drawing the trefoil knot on the associahedron. Reverse engineering th…

Along the way, I also talk about stacks as Lie groupoids up to Morita equivalence, as well as the infinitesimal counterpart to groupoids: Lie algebroids.
4/4
This time, I look at the other side of the story: how to encode a quotient stack in terms of an L-infinity algebra which is concentrated in degrees 0 and 1.
3/4
In the first part, I told you how the 'derived' zero locus of a function can be encoded by an L-infinity algebra which is concentrated in degrees 1 and 2.

Finally! The long-awaited sequel in my series of blog posts: How does a Lie algebra encode a space?

In the paper, I also take a closer look at this extension problem and relate it to the study of vector bundles on weighted projective space. 8/8
The cool thing is that the subcategories of connections that *do* extend over the entire vector space are not the same on either side of a castling equivalence. Hence, this gives a very simple method for producing examples of non-extendabl…
