平方度量是一类特殊的Finsler度量。它是度量范畴的率类,具有优良的几何性质。在本文中,我们讨论了所谓的奇异平方度量。这种度量的消失道格拉斯曲率的特征。此外,还利用一种特殊的度量变形--变形,给出了大量的解析算例。
Square metricsare a special class of Finsler metrics. It is the rate kind of metric category to be of excellent geometrical properties. In this paper, we discuss the so-called singular square metrics. A characterization for such metrics to be of vanishing Douglas curvature is provided. Moreover, many analytical examples are achieved by using a special kinds of metrical deformations called-deformations.
