On the 4th of April 2019, at 10:15 a.m.
Carlos
Perez (IFT)
will give a talk on
"An
introdution to tensor models"
Abstract
Proposed
by Ambjon,
Durhuus and
Jonsson as a
generalization
of matrix
models, tensor
models were
further
propelled by
Gurau, who
found their
large
N-extension,
and
collaboratos.
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
ensamble 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.
seminar
takes place on Thursdays from 10:15 a.m. to 12:00 in
the room 2.23 of the main building of the Faculty of
Physics (the 2nd floor), Pasteur Str. 5, Warszawa.
