Over the last months, I took a break from this blog project in order to write my Master’s dissertation on Disorder and topology in spin systems. I since started my PhD at Aalto University in Finland and am working hard on other projects. I finally found some time to able to return with this third blog post, where I will continue with notes from my reading of Heunen and Vicary’s Categories for quantum theory, by going over chapter 2, on the linear structure of monoidal categories. Stay tuned for more in the near future. Next post should be a large one regarding braided categories.
