Query: On the canonical structure of general relativity with a limiting
  curvature and its relation to loop quantum gravity   Chamseddine and Mukhanov recently proposed a modified version of general
relativity that implements the idea of a limiting curvature. In the spatially
flat, homogeneous, and isotropic sector, their theory turns out to agree with
the effective dynamics of the simplest version of loop quantum gravity if one
identifies their limiting curvature with a multiple of the Planck curvature. At
the same time, it extends to full general relativity without any symmetry
assumptions and thus provides an ideal toy model for full loop quantum gravity
in the form of a generally covariant effective action known to all orders. In
this paper, we study the canonical structure of this theory and point out some
interesting lessons for loop quantum gravity. We also highlight in detail how
the two theories are connected in the spatially flat, homogeneous, and
isotropic sector.
