Description: in this lecture, prof. liu continues discussion of theories whose fields are built out of matrices. when the rank n of the matrices become large, observables can be expanded in 1 / n. this large n expansion can be organized in terms of topology of feynman diagrams. instructor: hong liu.

(PDF) A Large N Expansion For Gravity | Fabrizio Canfora - Academia.edu When the rank n of the matrices become large, observables can be expanded in 1 / n. this large n expansion can be organized in terms of topology of feynman diagrams. In contrast, the riemann surfaces that arise in the large n expansion are not smooth at all; they are tiled by feynman diagrams and in the perturbative limit, ⌧ 1, the diagrams with the fewest vertices dominate. In large n gauge theories, the 1/n expansion is tantamount to sorting the feynman diagrams according to their degree of planarity, that is, the minimal genus of the plane onto which the diagram can be mapped without any crossings.

String theory and holographic duality, lec7. freely sharing knowledge with learners and educators around the world. learn more. this resource contains information regarding structure of large n expansion. In quantum field theory and statistical mechanics, the 1/n expansion (also known as the " large n " expansion) is a particular perturbative analysis of quantum field theories with an internal symmetry group such as so (n) or su (n). 7. structure of large n expansion (m i t) 7. structure of large n expansion (m i t) course: string theory and holographic duality (m i t) discipline: basic and health sciences institute : mit instructor (s) : prof. hong liu level: graduate. I have some understanding of how the large $n$ expansion works but feel like i'm missing the most important concepts. for example, i understand that in qcd the order of the diagram in $n$ depends only on it's topology (euler characteristic $\chi$).
