A short note on extended probability theory
Johan Noldus
We propose two distinct interpretations of extended probabilities which are realistic for the physical world.
Interpretation of quantal manifolds
Johan Noldus
In quantum gravity, one looks for alternative structures to spacetime physics than ordinary real manifolds. Here, we propose an alternative universal construction containing the la…
Free Fermions on causal sets
Johan Noldus
We construct a Dirac theory on causal sets; a key element in the construction being that the causet must be regarded as emergent in an appropriate sense too. We further notice that…
Lorentzian Manifolds and Causal Sets as Partially Ordered Measure Spaces
Luca Bombelli, Johan Noldus, Julio Tafoya
We consider Lorentzian manifolds as examples of partially ordered measure spaces, sets endowed with compatible partial order relations and measures, in this case given by the causa…
A new topology on the space of Lorentzian metrics on a fixed manifold
Johan Noldus
We give a covariant definition of closeness between (time oriented) Lorentzian metrics on a manifold M, using a family of functions which measure the difference in volume form on o…
Should quantum theory change in the light of gravity?
Johan Noldus
In this paper, we study implications of the geometrical nature of space- time for some of the basic tenets of quantum mechanics. That is, we study two different implications of the…
