Abstract

. In this paper, we study the approximation properties of 2 π -periodic functions in a seminormed space. We use a general matrix method of summability, and the moduli of continuity in the seminormed space as a measure of approximation. Our results generalize and improve some of the previous results available in the literature.

半形空间中函数的三角逼近

。本文研究了半形空间中2 π周期函数的逼近性质。我们使用可和性的一般矩阵方法，并将半成形空间中的连续模作为逼近的度量。我们的研究结果概括并改进了文献中已有的一些结果。

期刊介绍： ''Mathematical Inequalities & Applications'' (''MIA'') brings together original research papers in all areas of mathematics, provided they are concerned with inequalities or their role. From time to time ''MIA'' will publish invited survey articles. Short notes with interesting results or open problems will also be accepted. ''MIA'' is published quarterly, in January, April, July, and October.
