We discuss how local prequantum field theories with boundaries can be described in terms of n-fold correspondence diagrams in the infinity-topos of smooth stacks equipped with higher circle bundles. This places us in a ...
The aim of this thesis is to define and use the notion of a sheaf to define cohomology theories. These sheaf cohomology theories will be defined in an axiomatic way and then showed to be unique. Then a few of such cohomology ...
This thesis has two aims. The primary aim is to introduce the intersection product method of evaluating families of Feynman integrals, and to put it into physical and mathematical context. In order to achieve this, we ...
