Jonathan Heckman, Covariant Non-Commutative Geometry from String Theory ...

Δημοσιεύτηκε στις 3 Φεβ 2013

This
is the talk given by Jonathan Heckman at Strings 2012. In it, Heckman
discusses how one can derive a noncommutative geometry from string
theory. I don't believe a reference for this talk has been released
yet, but some of the ideas are (I believe) in this paper:

http://arxiv.org/abs/1005.3033

These are also relevant:

http://arxiv.org/abs/hep-th/0312171
http://arxiv.org/abs/1104.2605

EDIT: As pointed out by Patrick Tam below, here is a reference:

http://arxiv.org/abs/1401.1810

The
Strings conference is the largest annual meeting of string theorists,
and includes the biggest names in the subject giving talks on
advancements made in essentially every aspect of the theory. Anyone who
is interested in the subject should be quite interested in these talks!
(I'm hoping to actually attend the conference this year in Seoul... but
we'll see...)

The lectures can be found, viewed, and downloaded
from free from the website for the Ludwig-Maximilians-Universität
München, which was the venue for the conference in 2012). In particular,
there are many more lectures which do not appear in this playlist
(these are merely the lectures I personally find most interesting).
Their website can be found here:

Gwendolyn Barnes: "A category theoretic framework for noncommutative and...

Δημοσιεύτηκε στις 10 Μαΐ 2016

Talk given as part of Categories Logic and Physics Scotland: http://homepages.inf.ed.ac.uk/cheunen...

Observations
from flux compactifications of closed string theory suggest that a
theory of gravity at quantum scales may be not only noncommutative but
also nonassociative. Having an abstract understanding of geometry is one
approach to help us to describe a noncommutative and nonassociative
theory of gravity. In work together with Alexander Schenkel and Richard
J. Szabo we have appealed to the tools of category theory to better
understand the mathematical structures underlying noncommutative and
nonassociative deformations of spacetime geometry.

Masoud Khalkhali, Curvature in Noncommutative Geometry

                



Masoud Khalkhali, Curvature in Noncommutative Geometry

Δημοσιεύτηκε στις 8 Οκτ 2014

In
this talk Masoud Khalkhali, of University of Western Ontario, discusses
various topics related to the notion of curvature for noncommutative
tori, including scalar curvature, the Gauss-Bonnet theorem, and the
Einstein-Hilbert action.

References relevant to this talk include:

http://arxiv.org/abs/1110.3511
http://arxiv.org/abs/1301.6135
http://arxiv.org/abs/1111.1358
http://arxiv.org/abs/1005.4947
http://arxiv.org/abs/1410.0475
http://arxiv.org/abs/1307.5367

This
talk was given at the Perimeter Institute in May of 2014. This talk, as
well as many, MANY others can be downloaded at the PI online video
library -- follow the link below:

http://www.perimeterinstitute.ca/vide...

A pdf for this talk can be found at the following link:

http://pirsa.org/pdf/loadpdf.php?pirs...

Khalkhali's abstract for this talk is as follows:

"After
the seminal work of Connes and Tretkoff on the Gauss-Bonnet theorem for
the noncommutative 2-torus and its extension by Fathizadeh and myself,
there have been significant developments in understanding the local
differential geometry of these noncommutative spaces equipped with
curved metrics. In this talk, I will review a series of joint works with
Farzad Fathizadeh in which we compute the scalar curvature for curved
noncommutative tori and prove the analogue of Weyl's law and Connes'
trace theorem. Our final formula for the curvature matches precisely
with the one computed independently by A. Connes and H. Moscovici. I
will then report on our recent work on the computation of scalar
curvature for noncommutative 4-tori (which involves intricacies due to
violation of the Kähler condition). We show that metrics with constant
curvature are extrema of the analogue of the Einstein–Hilbert action. A
purely noncommutative feature in these works is the appearance of the
modular automorphism from Tomita–Takesaki theory of KMS states in the
final formulas for the curvature."
