| Abstract | We discuss the minimal model program for Q-factorial surfaces in
positive characteristic. More precisely, we show the cone theorem and the
contraction theorem for these surfaces. These two theorems also hold for
the case where the characteristic is zero. But our proofs need the
Frobenius map. |
