L（IR）中卷积函数类在L_2（IR）中的平均σ－K宽度

Average σ- K Width of Convolution Function Class of L(IR) in L_2(IR).

本文研究了Ｌ（ＩＲ）中的卷积函数类在Ｌ＿２（ＩＲ）中的平均σ－Ｋ宽度且得到一些精确结果．同时，对非卷积情形，得到一些渐近结果．

in this paper, we study the average σ- K widths of the convolution classesof functions of L(IR) in L￣2 (IR) and obtain some exact results. Meanwhile, for the non-convolution case, we also obtain some asymptotic results.
