Project Components

There are two components to this project.

Component 1: Development of New Theory

  1. Develop and extend the striking new theory, created by the PI in the last few years, which studies triangulated categories via metrics and approximations.

In the case of Component 1, the novel idea of appropriately using metrics has already allowed the PI to prove several difficult conjectures, the most recent just a few weeks ago. The potential of the new theory is immense, and this project aims to extend the scope of the methods and apply them widely.

The project also aims to work out the implications of a surprising theorem proved by the methods, which shows that the derived category of perfect complexes and the bounded derived category of coherent sheaves are constructible from each other, as triangulated categories, by an explicit recipe. This theorem flies in the face of accepted wisdom, which viewed the two categories as totally different. Thus, a whole body of work, analyzing the many differences between these derived categories, needs to be carefully revisited and reconsidered in the light of the new construction.

Component 2: Understanding Fourier-Mukai Functors

  1. Build on very recent work to better understand which functors are Fourier-Mukai and which aren't.

The Fourier-Mukai transforms of Component 2 have a long and venerable history, with beautiful work by many authors. However, there were novel techniques introduced in a couple of recent articles, and the project plans to deploy them more widely. The aim is for a breakthrough in the area, leading to a better understanding of which exact functors are Fourier-Mukai and which aren't.
