A note on interior $W^{2,1+\varepsilon}$ estimates for the Monge-Ampere equation
By a variant of the techniques introduced by the first two authors in [DF] to prove that second derivatives of solutions to the Monge-Ampere equation are locally in $L\log L$, we obtain interior $W^{2,1+\varepsilon}$ estimates.
