Query: Alternative derivation of Krasnov's action for general relativity   Starting from Plebanski's action for general relativity with cosmological
constant, we show that by integrating out all the auxiliary fields Krasnov's
action immediately emerges. We also perform the Hamiltonian analysis of the
latter and show that the constraints are those of the Ashtekar formalism.
