Seminarium KMMF "Teoria Dwoistości"

Proposed by Ambjørn, Durhuus and Jonsson as a generalisation of matrix models, tensor models were further propelled by Gurau, who found their large-N expansion, and collaborators. This talk will be devoted to some field theory techniques for tensor models. To wit: A powerful method, by Grosse and Wulkenhaar, that has led to solvable and solved models, consists in combining the U(N)-Ward identity for matrix ensemble of size N, with their Dyson-Schwinger equations. In this talk, I will implement this idea in order to derive the loop equations of (certain class of) quartic tensor models.
