Minimal model program for algebraically integrable foliations on klt varieties

We prove the contraction theorem and the existence of flips for algebraically integrable foliations on klt varieties which strengthen a result of Cascini and Spicer by removing the assumption on termination of flips. Thus we establish the minimal model program for algebraically integrable foliations on klt varieties unconditionally. As a consequence, for algebraically integrable foliations polarized with ample divisors, we prove the existence of minimal models and Mori fiber spaces either when the ambient variety is klt or in the sense of Birkar-Shokurov. We also show the existence of a Shokurov-type polytope for algebraically integrable foliations.
