Hi, has anybody studied the papers from Eyo Eyo Ita III? E.g. recently http://arxiv.org/abs/0805.4004v3 Canonical quantization of Plebanski gravityEyo Eyo Ita III (Submitted on 26 May 2008 (v1), last revised 30 Apr 2010 (this version, v3)) Abstract: In this paper we show that the Plebanski theory of gravity implies a theory dual to the Ashtekar variables where the antiself-dual Weyl curvature is the fundamental momentum space variable. The dual theory implies the Einstein equations modulo the initial value constraints, and appears to be consistent in the Dirac sense. Using the dual theory we have obtained a reduced phase space for gravity through implementation of the initial value constraints. Additionally we have computed the classical dynamics and have performed a quantization on this space, constructing a Hilbert space of states for vanishing cosmological constant. Finally, we have clarified the canonical structure of the dual theory in relation to the Ashtekar theory. His papers are usually rather long and elaborated, but they do not seem to be considered by any other LQG specialist. I have never seen him collaborating with other LQG people nor have I found any peer reviewed articles - except one from 2008.
