Repeatedly Rovelli posts papers that are not boring.

This one shows a lot of progress towards the GR limit and also a Feynman-style presentation with what I think is wide appeal

But first, there is this Russian filmmaker Ilya Khrzhanovsky

http://en.wikipedia.org/wiki/Ilya_Khrzhanovsky

who is currently making a $10 million budget documentary about Lev Landau. Interesting character. 1908-1968. Nobel condensed matter.

Could this Ilya be the same Ilya who is thanked for hospitality in the acknowledgment section of Rovelli's paper? And what significance the date 1942?

Here's the paper:

Carlo Rovelli

8 pages, 3 figures

(Submitted on 10 Oct 2010)

"New progress in loop gravity has lead to a simple model of 'general-covariant quantum field theory'. I sum up the definition of the model in self-contained form, in terms accessible to those outside the subfield. I emphasize its formulation as a generalized topological quantum field theory with an infinite number of degrees of freedom, and its relation to lattice theory. I list the indications supporting the conjecture that the model is related to general relativity and UV finite."

Andrei Losev is also thanked:

http://arxiv.org/find/hep-th/1/au:+Losev_A/0/1/0/all/0/1

some 60 papers---much elegant math (Riemann-Roch Hirzbruch TQFT...) plenty of stringery plenty of algebra, algebraic geometry, topology

Maybe this Ilya is not the filmmaker Ilya but some surprise departure from the everyday is indicated---or is it an unlikely concatenation of typographical errors?
