Causal Sets in 2 dimensions
Speaker(s): Lisa Glaser
Abstract: Calculating the path integral over all causal sets will take a lot of computing power, and requires a way to suppress non-manifold like causal sets. To work towards these goals we can start by taking the path integral over a restricted class of causal sets, the 2d orders. Using these have found a ph... read more

Random and Fuzzy
Speaker(s): Lisa Glaser
Abstract: In this lecture I will introduce non-commutative geometry in the form of fuzzy spaces and explain how we have begun examining random fuzzy spaces using Markov Chain Monte Carlo simulations. Doing so leads us to consider a complicated matrix model, with even more complicated observables on it. A part... read more

Random non-commutative geometry
Speaker(s): Lisa Glaser
Abstract: The collection of all Dirac operators for a given fermion space defines its space of geometries.  Formally integrating over this space of geometries can be used to define a path integral and a thus a theory of quantum gravity.  In general this expression is complicated, however f... read more

PIRSA:15090083  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A chain of geometries
Speaker(s): Lisa Glaser
Abstract: The path integral is a very elegant formulation of quantum theory. It can also be an incredibly useful one, since it allows us to use methods of statistical physics, like computer simulations. In this talk I will introduce the subject of Markov Chain Monte Carlo simulations to solve the path int... read more

PIRSA:13100063  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A causal set action
Speaker(s): Lisa Glaser
Abstract: Causal set theory is discrete, fully covariant theory of quantum gravity. The discrete framework makes it necessary to reformulate continuum concepts. One of these concepts is that of a derivative operator. It is possible to define a derivative operator in causal sets that in the continuum l... read more
