Let a > 0, a ≠ 1 and f (x) = loga (x2-2x + 3) have the minimum value, then the solution set of inequality loga (x-1) > 0 is______ ．
From a ＞ 0, a ≠ 1, the function f (x) = loga (x2-2x + 3) has the minimum value, we can know that a ＞ 1, so the inequality loga (x-1) ＞ 0 can be transformed into X-1 ＞ 1, that is, X ＞ 2
