对于V.V. Shokurov猜想的最小对数差值的有界性的一种解释是，一个变量在其闭点上的最小对数差值定义了一个下半连续函数。我们对不超过3维的变数和任意维的环变数检验了这种下半连续性。
An explanation to the boundness of minimal log discrepancies conjectured by V.V. Shokurov would be that the minimal log discrepancies of a variety in its closed points define a lower semi-continuous function. We check this lower semi-continuity behaviour for varieties of dimension at most 3 and for toric varieties of arbitrary dimension.
