... typical problem demands a characterizations of all maps on a certain set of matrices that preserve some function, subset or a relation. If the studied maps are bijective by the assumption, then the characterization of the maps involved is often easier to obtain. In the case of certain preservers of ...

... somewhat simpler than the LSZ discussion. But it relies on the identification of the initial and final states with their leading order expansions. We can refine this by thinking about the structure of the perturbation expansion. The LSZ formula systematizes this. LSZ has other virtues. Most importan ...

... Dichromatic state sum models and four-dimensional topological quantum field theories from pivotal functors There is a scarcity of four-dimensional topological state sum models. Apart from the Crane-Yetter model, defined in the 90s, little is known. In this talk, a family of invariants of four-dimens ...

... Lorentz scalar so that the theory is Lorentz invariant. Add one more requirement that the Lagrangian contains at most two space-time derivatives. We can conclude the most general Lagrangian is written as in Eq. (2.6) on P.3. Derive its Euler Eq. and we get (2.7). It’s called Klein-Gorden Equation. 5 ...
