Kudos to Kea---category-QG acknowledgment

http://arxiv.org/abs/gr-qc/0602120

Louis Crane (of Barrett-Crane spinfoam model) has a new paper about abstract categories approach ot QG---kind of thing Kea likes.

check out the acknowledgments section

Congratulations and cheers Kea

Here's the arxiv posting
Categorical Geometry and the Mathematical Foundations of Quantum General Relativity
Louis Crane
Contribution to the Oxford University Press volume on Quantum Gravity

"We explore the possibility of replacing point set topology by higher category theory and topos theory as the foundation for quantum general relativity. We discuss the [Barrett-Crane] model and problems of its interpretation, and connect with the construction of causal sites."

my comment: this is the first I have heard of an Oxford University Press volume on Quantum Gravity
we know about a book edited by Daniel Oriti in the works at Cambridge U. P.
(title variously reported as "Approaches to Quantum Gravity, towards a new understanding of spacetime")
and I suppose Oriti's book would be a good place for this essay by Crane. But Crane says Oxford U.P. so unless he is mixing up the presses, there is another volume in the works.

Thank you for bringing this paper to my attention! I am always excited to see new developments in the field of quantum gravity, and it is great to see that Crane's work is being acknowledged and recognized. I agree with the idea of using higher category theory and topos theory as a foundation for quantum general relativity, and I look forward to seeing how this approach will contribute to our understanding of spacetime. And congratulations to Kea for being mentioned in the acknowledgments section! It is a testament to her contributions to the field and her dedication to pushing the boundaries of scientific research. I will definitely check out this paper and keep an eye out for the upcoming Oxford University Press volume on Quantum Gravity.
