초록

Let Q∈{C}^2 : R→[0,∞) be an even function. Then we will consider the exponential weights w(x)=exp(-Q(x)) in the weight class from [2]. In the paper, we will give some relations among exponential weights in this class and introduce a new weight subclass. In addition, we will investigate some properties of the typical and specific weights in these weight classes.

In addition, we will investigate some properties of the typical and specific weights in these weight classes.
