## Resumen

A search for CP violation in the phase-space structures of D
^{0} and D-0 decays to the final states K
^{-}K
^{+}π
^{-}π
^{+} and π
^{-}π
^{+}π
^{+}π
^{-} is presented. The search is carried out with a data set corresponding to an integrated luminosity of 1.0 fb
^{-1} collected in 2011 by the LHCb experiment in pp collisions at a centre-of-mass energy of 7 TeV. For the K
^{-}K
^{+}π
^{-}π
^{+} final state, the four-body phase space is divided into 32 bins, each bin with approximately 1800 decays. The p-value under the hypothesis of no CP violation is 9.1%, and in no bin is a CP asymmetry greater than 6.5% observed. The phase space of the π
^{-}π
^{+}π
^{+}π
^{-} final state is partitioned into 128 bins, each bin with approximately 2500 decays. The p-value under the hypothesis of no CP violation is 41%, and in no bin is a CP asymmetry greater than 5.5% observed. All results are consistent with the hypothesis of no CP violation at the current sensitivity.
